## Background
RELATED APPLICATIONS
This application claims the benefit of Korean Patent Application No. 10-2013-0105698, filed on Sep. 3, 2013, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
BACKGROUND
1. Field
One or more embodiments of the present invention relate to an ultrasound probe and a method of operating the ultrasound probe, and more particularly, to an ultrasound probe connected to various diagnostic apparatuses and a method of operating the ultrasound probe.
2. Description of the Related Art
Ultrasound systems irradiate an ultrasonic signal generated from a transducer of an ultrasound probe onto an internal part of an object and receive information of an echo signal reflected from the internal part of the object, thereby acquiring an image of the internal part of the object. In particular, ultrasound systems are used for the medical purpose of observing the inside of an object, detecting a foreign material, assessing internal injuries, imaging fetuses and the like.
Ultrasound systems have stabilities higher than those of diagnostic apparatuses using X-rays, display an image in real time, and are safe because there is no exposure to radioactivity, and thus may be widely used on their own and/or along with other medical image diagnostic apparatuses.
It may be inconvenient for a user to acquire an ultrasound image of an object by using an ultrasound probe due to a communication cable used to connect the ultrasound probe and a diagnostic apparatus. Further, the communication cable poses challenges for manufacturers of the probes and of the diagnostic apparatuses, as the real and imaginary impedances of the cable and the connectors of diagnostic apparatuses must be matched very carefully, in order to avoid noise levels and the like, which may affect the resulting image quality to be displayed by or on the diagnostic apparatuses, in particular in embodiments where signal processing to generate image data is achieved in the diagnostic apparatuses and the response signal is transmitted from the probe to the diagnostic apparatus.
To improve operability of the ultrasound probe by removing the cable and/or the inconveniences caused by the communication cable, there may be a need for a wireless ultrasound probe that is connected to an ultrasound diagnostic apparatus by wireless communication.
Moreover, when a wireless (or wired) ultrasound probe is subordinate to one ultrasound diagnostic apparatus, since each of a plurality of ultrasound diagnostic apparatuses needs to include a plurality of wireless ultrasound probes, there are problems in that manufacturing costs are high and management is difficult.
Different probes and/or types of probes, which are all subordinate to one particular diagnostic apparatus, cannot be employed with any other diagnostic apparatus. Consequently, for each diagnostic apparatus, the hospital or other facility needs to acquire a full range of probes for each diagnostic apparatus, which increases costs. In relation to management it is noted, that, for instance, an operator must be aware precisely to which diagnostic apparatus a chosen probe for examination of a particular object belongs. Otherwise, communication problems will occur and medical imaging may turn out not to be possible, and a person as the object under examination will be caused concerns and possibly even anxiety, when the medical equipment does not immediately appear to be functioning properly, when initiating the examination. Thus, there is a need for a ultrasound probe, for instance a wireless ultrasound probe, that is not subordinate to one ultrasound diagnostic apparatus but may communicate with a plurality of ultrasound diagnostic apparatuses.
Based in these considerations, the inventive concept of the present disclosure may be equally applicable in embodiments of probes employing wired communication connections with diagnostic apparatuses, for instance when signal processing is performed in the probes.
SUMMARY
One or more embodiments of the present invention include an ultrasound probe which is connectable to various diagnostic apparatuses and a method of operating the ultrasound probe.
One or more embodiments of the present invention include an ultrasound probe for generating transmission data that may be processed by a diagnostic apparatus connected to the ultrasound probe based on information regarding the diagnostic apparatus and transmitting the transmission data to the diagnostic apparatus by using a communication method and/or a transmission signal format used by the diagnostic apparatus, and a method of operating the ultrasound probe. Connection between the diagnostic apparatus and the probe, and communications between the probe and the diagnostic apparatus may be wired or wireless.
Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.
According to one or more embodiments of the present invention, there is provided a method of operating an ultrasound probe, the method comprising: transmitting an ultrasound signal to an object and receiving a response signal reflected from the object; determining at least one type of data that a diagnostic apparatus is arranged to process, which diagnostic apparatus is connected to the ultrasound probe, from a plurality of various diagnostic apparatuses, which are connectable to the ultrasound probe; generating transmission data from the response signal in correspondence to the determined type of data; and transmitting the transmission data to the diagnostic apparatus. It is noted in this respect that the steps of the method are not necessarily sequentially presented above and defined in the appended claims. For instance, the step of determining a type of data for the connected diagnostic apparatus may precede the step of transmitting the ultrasound signal and receiving the response or echo signal back from (the interior) of the object. Types of data for a range of various diagnostic apparatuses may even be stored in the probe, even before any transmission of ultrasound signals and/or reception of response signals is performed. Embodiments of the present disclosure having these features exhibit the advantage without these features that the cooperation between a single probe and a plurality of various types of diagnostic apparatuses is made possible, and vice versa.
The determining of the at least one type of data that the connected diagnostic apparatus is arranged to process, may comprise: acquiring at least one of: a type of data, which the diagnostic apparatus is arranged to process, a wireless communication method used by the diagnostic apparatus, a wired communication method used by the diagnostic apparatus, and an identifier of the diagnostic apparatus. Embodiments in this aspect of the present disclosure having these features exhibit the advantage or benefit over embodiments without these features without such features that initialisation of the communication between the probe and the diagnostic apparatus may immediately yield improved cooperation, and allow plural diagnostic apparatuses and probe to cooperate using different communication methods and possibly using storage and/or mapping of the suitable types transmission data to which a probe may be connected beforehand.
The method may further include, after acquiring the identifier of the diagnostic apparatus: storing the identifier of each of the plurality of various diagnostic apparatuses, that are connectable to the ultrasound probe, and mapping the stored identifiers onto at least one of: at least one type of data that each of the plurality of diagnostic apparatuses, that is associated with the identifier, is arranged to process; and a wired or wireless communication method used by each of the plurality of diagnostic apparatuses. Embodiments in this aspect of the present disclosure having these features exhibit the advantage or benefit over embodiments without these features that a match between the suitable type of transmission data and the one type of various diagnostic apparatuses may be pre-stored, after which only an ID of the diagnostic apparatus is required to be obtained, to thereafter adapt the probe and the manner of functioning thereof to the type of an actually connected diagnostic apparatus.
The method may further include that the generating of the transmission data comprises using at least one image processing unit of the ultrasound probe for processing the response signal to generate the transmission data from the response signal in correspondence with at least one type of data that the connected diagnostic apparatus is arranged to process.
The ultrasound probe may include at least one image processing unit for processing the response signal in at least two subsequent signal and/or image processing steps at least towards generating an image, wherein the generating of the transmission data may include: selecting a number of subsequent signal and/or image processing steps for processing of the response signal, necessary for generating the transmission data corresponding to the determined type of data; and generating the transmission data by using the selected signal and/or image processing steps. Embodiments in this aspect of the present disclosure having these features exhibit the advantage or benefit over embodiments without these features that of all the subsequent steps to process the response signal to obtaining ultrasound images, some may be performed in or by the probe, and some may be performed in or by the diagnostic connected apparatus. Such complementary cooperation between probes and diagnostic apparatuses is elegant allows tailor made cooperation between the probe and the diagnostic apparatus, based on essentially the capabilities of the actually connected diagnostic apparatus to promote processing of subsequent signal and/or image processing steps further towards obtaining an ultrasound image, thereby relieving load of and/or power consumption by the probe. Further, such diagnostic apparatuses may exhibit improved shielding or more powerful processors, in comparison with the relatively small size probes, to allow probes to generate ultrasound images or enable the probes to stop processing at some stage intermediate between the response signal and furnishing the ultrasound images and leaving as many steps in these subsequent processing steps as possible to the diagnostic device, adding to the versatility of the thus obtained cooperation between the probe and the actually connected diagnostic apparatus.
The generating of the transmission data may include: preventing the at least one signal and/or image processing unit from performing any other steps than the selected number of signal and/or image processing steps. Embodiments in this aspect of the present disclosure having these features exhibit the advantage or benefit over embodiments without these features of a reduction of power consumption of several processors which may be powered down. A single processor may be prevented from having to perform all steps to arrive at the ultrasound image, thus reducing load of and power consumption by such a single processor. The at least one processor may process signals or images.
The transmitting of the transmission data may include: determining a communication method used by the diagnostic apparatus based on the determined type of data that the diagnostic apparatus is arranged to process; and transmitting the transmission data by using the determined communication method. Embodiments in this aspect of the present disclosure having these features exhibit the advantage or benefit over embodiments without these features that unselected communication units may be opowered down, adding to power savings.
The determining of the wireless communication method used by the diagnostic apparatus may include: determining at least one of wireless LAN, Wi-Fi, Bluetooth, Zigbee, Wi-Fi Direct (WFD), UWB, infrared data association (IrDA), Bluetooth low energy (BLE), near field communication (NFC), wireless broadband Internet (Wibro), world interoperability for microwave access (WiMAX), shared wireless access protocol (SWAP), wireless gigabit allicance (WiGig), and radio frequency (RF) communication as the wireless communication method used by the diagnostic apparatus.
The transmitting of the transmission data may comprise using at least one communication unit of the ultrasound probe for transmitting the transmission data by using at least one of different communication methods in correspondence with the at least one type of data that the various diagnostic apparatuses, which are connectable to the ultrasound probe, are arranged to process.
The ultrasound probe may include a plurality of communication units for transmitting the transmission data, for instance by using different wireless communication methods, wherein the transmitting of the transmission data comprises: selecting at least one communication unit corresponding to the communication method used by the diagnostic apparatus from the plurality of communication units corresponding to the determined type of data, that the diagnostic apparatus is arranged to process.
The transmitting of the transmission data may include: determining a first communication method and a second communication method that are used by the diagnostic apparatus based on the determined type of data that the diagnostic apparatus is arranged to process; selecting a first communication unit corresponding to the first communication method and a second communication unit corresponding to the second communication method from the plurality of communication units; and transmitting the transmission data by using the first communication unit and optionally transmitting and/or receiving at least one of state information data of the ultrasound probe and control data of the diagnostic apparatus by using the second communication unit. Embodiments in this aspect of the present disclosure having these features exhibit the advantage or benefit over embodiments without these features that communications flows can be generated using the different communication units, thereby optimizing the total transfers, without interference or interruption.
According to one or more embodiments of the present invention, there is provided an ultrasound probe including: an ultrasound transceiving unit for transmitting an ultrasound signal to or into an object and receiving a response signal reflected from the object or from within the object; a control unit for determining at least one type of data that a diagnostic apparatus is arranged to process, which diagnostic apparatus is in use connected to the ultrasound probe, from a plurality of various diagnostic apparatuses, which are connectable to the ultrasound probe; a transmission data generating unit for generating transmission data from the response data in correspondence with the determined type of data; and a communication unit for transmitting the transmission data to the diagnostic apparatus.
The control unit may determine at least one type of data that the connected diagnostic apparatus is arranged to process, by acquiring at least one of: a type of data which the diagnostic apparatus is arranged to process; a wireless communication method used by the diagnostic apparatus, a wired communication method used by the diagnostic apparatus; and an identifier of the diagnostic apparatus.
The ultrasound probe wherein the control unit acquires the identifier of the diagnostic apparatus, may further include: a storage unit for storing the identifier of each of the plurality of various diagnostic apparatuses that are connectable to the ultrasound probe, and mapping the stored identifiers onto at least one of: at least one type of data that each of the plurality of various diagnostic apparatuses that is associated with the identifier, is arranged to process; and a wired or wireless communication method used by each of the plurality of diagnostic apparatuses.
The transmission data generating unit may include at least one image processing unit for processing the response signal to generate the transmission data from the response signal in correspondence with at least one type of data that the various diagnostic apparatuses, which are connectable to the ultrasound probe, are arranged to process, and wherein, when the transmission data generating unit comprises a plurality of image processing units for processing the response signal, the control unit controls the transmission data generating unit to select at least one of the plurality of image processing units necessary for generating the transmission data corresponding to the determined type of data, and generate the transmission data by using the selected at least one image processing unit.
The control unit may disable the image processing units excluding the selected at least one image processing unit.
The control unit may control the communication unit to determine a communication method used by the diagnostic apparatus based on the determined type of data that the diagnostic apparatus is arranged to process, and transmit the transmission data by using the determined communication method.

FIG. 1 is a diagram of a general ultrasound apparatus according to a wired embodiment of the present invention.
Referring to FIG. 1, the general ultrasound apparatus includes an ultrasound probe 10 and a diagnostic apparatus 20 connected to the ultrasound probe 10 via a communication cable 15.
The ultrasound probe 10 transmits an ultrasound signal to or into an object according to a control signal transmitted from the diagnostic apparatus 20, receives a response signal (or an ultrasound echo signal) reflected from the object, and forms a receiving signal. The ultrasound probe 10 focuses the ultrasound signal, forms ultrasound image data from the receiving signal, and transmits the ultrasound image data to the diagnostic apparatus 20.
The diagnostic apparatus 20 may form and display an ultrasound image by using the ultrasound image data transmitted from the ultrasound probe 10.
As indicated above, there is a need for a preferably wireless ultrasound probe that is not subordinate to one ultrasound diagnostic apparatus but may communicate with a plurality of ultrasound diagnostic apparatuses. However, a type of data transmitted from the ultrasound probe 10 to the diagnostic apparatus 20 and a preferably wireless communication method used to transmit the data are fixed for any combination of a probe and the diagnostic apparatus to which the probe belongs or is subordinate to. Thus, a diagnostic apparatus that may be connected to one ultrasound probe is very limited.
One or more embodiments of the present invention provide an ultrasound probe that may be connected to various diagnostic apparatuses by selectively outputting an appropriate type of data according to a characteristic of a diagnostic apparatus connected to the ultrasound probe.
FIG. 2 is a conceptual diagram for explaining an ultrasound system including an ultrasound probe 200 according to an embodiment of the present invention.
Referring to FIG. 2, the ultrasound probe 200 according to an embodiment of the present invention may be used by being connected to a plurality of diagnostic apparatuses 31, 32, 33, and 34 having various characteristics. The probe may be connected through wires or cables with any one of the diagnostic apparatuses 31-34, or wirelessly.
In this regard, a “diagnostic apparatus” is an apparatus that is connected to the ultrasound probe 200 by wire or wirelessly and provides a user with an ultrasound image by using ultrasound image data received from the ultrasound probe 200.
In this regard, each of the plurality of diagnostic apparatuses 31, 32, 33, and 34 may be connected together or alone to the ultrasound probe 200 and provide a user with an ultrasound image by using ultrasound image data received from the ultrasound probe 200.
Each of the plurality of diagnostic apparatuses 31, 32, 33, and 34 may be configured as a cart type diagnostic apparatus as well as a portable diagnostic apparatus. The portable diagnostic apparatus may include a picture archiving and communication system (PACS) viewer, a hand-carried cardiac ultrasound (HCU) device, a smart phone, a lap-top computer, a personal digital assistant (PDA), and a tablet personal computer (PC), but is not limited thereto.
Each of the plurality of diagnostic apparatuses 31, 32, 33, and 34 that may be connected to the ultrasound probe 200 according to an embodiment of the present invention may process ultrasound image data received from the ultrasound probe 200, generate an ultrasound image, and display the ultrasound image, or may perform only an image display function without having an image processing function. That is, each of the plurality of diagnostic apparatuses 31, 32, 33, and 34 may include a display apparatus that receives an image from the ultrasound probe 200 and displays the image on a screen without performing additional processing on the image.
For example, as shown in FIG. 2, the diagnostic apparatuses 31, 32, 33, and 34 that may be connected to the ultrasound probe 200 may be a cart type ultrasound diagnostic apparatus 31, a PC 32, a PDA 33, and a smart phone 34. The diagnostic apparatuses 31, 32, 33, and 34 of FIG. 2 process different types of ultrasound image data, and or may process the same ultrasound image data differently and/or may have different functionalities and/or performances.
The diagnostic apparatuses 31, 32, 33, and 34 may use different wireless communication methods. As shown in FIG. 2, wireless communication methods used by the diagnostic apparatuses 31, 32, 33, and 34 may include 60G, ultra wide band (UWB), WiFi, and Bluetooth.
One or more embodiments of the present invention may provide the ultrasound probe 200 that may be used by being connected to the diagnostic apparatuses 31, 32, 33, and 34 having various characteristics and a method of operating the ultrasound probe 200.
Therefore, the ultrasound probe 200 according to an embodiment of the present invention may output different types of ultrasound image data according to the diagnostic apparatuses 31, 32, 33, and 34 and in correspondence with a type of data, which the particular diagnostic apparatus is arranged to process. The ultrasound probe 200 according to an embodiment of the present invention may transmit ultrasound image data by using different wireless communication methods according to one of the plurality of the diagnostic apparatuses 31, 32, 33, and 34, to which the probe is at one particular time connected. The functioning of the probe is adapted to establish and maintain communications according to the wireless communication type and the type of data that the diagnostic apparatus is arranged to process.
A method of operating the ultrasound probe 200 according to an embodiment of the present invention that includes determining data types that may be processed by at least one of the plurality of diagnostic apparatuses 31, 32, 33, and 34 and transmitting transmission data corresponding to the determined data types to the diagnostic apparatuses 31, 32, 33, and 34 will now be described in detail with reference to FIGS. 3 through 5 below.
FIG. 3 is a flowchart of a method of operating the ultrasound probe 200 according to an embodiment of the present invention.
In operation S310, the ultrasound probe 200 transmits an ultrasound signal to an object and receives a response signal reflected from the object or from within the object.
The ultrasound probe 200 may be controlled by a control signal received from a diagnostic apparatus connected to the ultrasound probe 200. The ultrasound probe 200 according to an embodiment of the present invention may be connected to any one of a plurality of diagnostic apparatuses at one time, or to more than one of the diagnostic apparatuses, while the ultrasound probe 200 may be temporarily dependent upon at least one diagnostic apparatus according to a predetermined movement of a user.
The predetermined movement of the user may include connecting a communication cable of the ultrasound probe 200 to a diagnostic apparatus, approaching or contacting the ultrasound probe 200 to the diagnostic apparatus, selecting the diagnostic apparatus that is to be connected to the ultrasound probe 200, and selecting connection to the ultrasound probe 200 through the diagnostic apparatus.
That the ultrasound probe 200 is temporarily dependent upon the diagnostic apparatus may mean that the ultrasound probe 200 and the diagnostic apparatus are paired to form a session. The “session” may mean a logical connection for communication between the diagnostic apparatus and the ultrasound probe 200. To form the session, a process of having the diagnostic apparatus and the ultrasound probe 200 recognized each other by communicating a message therebetween occurs.
In operation S320, the ultrasound probe 200 acquires information regarding the diagnostic apparatus connected to the ultrasound probe 200.
The ultrasound probe 200 may acquire the information regarding the diagnostic apparatus through the session formed therebetween. The ultrasound probe 200 may acquire the information regarding the diagnostic apparatus by exchanging the message for forming the session therebetween. Thus, unlike in FIG. 3, operation S320 may precede operation S310. Pairing or other initial communications set-up may also occur prior to transmitting and receiving the ultrasound signals of step S310.
The information regarding the diagnostic apparatus may include at least one of a type of data that may be processed by the diagnostic apparatus, a wired or wireless communication method used by the diagnostic apparatus, and an identifier of the diagnostic apparatus but is not limited thereto. The information regarding the diagnostic apparatus may include, for example, function information of the diagnostic apparatus such as quality of an ultrasound image that may be provided by the diagnostic apparatus.
As an example, the ultrasound probe 200 may receive information regarding at least one of the type of data that may be processed by the diagnostic apparatus and the preferably wireless communication method used by the diagnostic apparatus from the diagnostic apparatus connected to the ultrasound probe 200. Wireless communication between the probe 200 and the diagnostic apparatus is only preferred to be able to dispense with hindering cables, but the invention is not limited thereto, and may include wired communication methods.
For example, the ultrasound probe 200 may request the diagnostic apparatus to transmit information regarding the diagnostic apparatus. The diagnostic apparatus may transmit the information regarding the diagnostic apparatus to the ultrasound probe 200 in response to a received request. For example, the diagnostic apparatus may transmit information regarding at least one of a type of data that is to be processed by the diagnostic apparatus, a communication method that is to be used by the diagnostic apparatus, a bandwidth that is to be used by the diagnostic apparatus, and a type of a communication channel that is to be used by the diagnostic apparatus to the ultrasound probe 200. The ultrasound probe 200 may process a response signal corresponding to the information received from the diagnostic apparatus to transmit transmission data to the diagnostic apparatus.
Alternatively, the ultrasound probe 200 may receive information relating to capability of the diagnostic apparatus from the diagnostic apparatus. The ultrasound probe 200 may receive information regarding all communication methods that may be supported by the diagnostic apparatus and types of all pieces of data that may be processed by the diagnostic apparatus. The ultrasound probe 200 may select at least one communication method and the type of at least one type of data from the received information. For example, the ultrasound probe 200 may select the communication method or the type of data that allows the diagnostic apparatus to provide an ultrasound image to a user at a highest resolution or at a highest frame rate. The ultrasound probe 200 may generate transmission data based on the selected type of data and transmit the transmission data to the diagnostic apparatus by using the selected communication method.
As another example, the ultrasound probe 200 may receive only the identifier of the diagnostic apparatus from the diagnostic apparatus connected to the ultrasound probe 200. The ultrasound probe 20 may acquire the information regarding the diagnostic apparatus by searching for information regarding the diagnostic apparatus previously stored in the ultrasound probe 200 based on the received identifier.
For example, the ultrasound probe 200 may map and store at least one of a type of data that may be processed by each of a plurality of diagnostic apparatuses and a communication method used by each of the diagnostic apparatuses and an identifier of each of the diagnostic apparatuses. The ultrasound probe 200 may acquire the identifier of the diagnostic apparatus from the diagnostic apparatus and search for information corresponding to the acquired identifier to establish the type of data that the diagnostic apparatus identified by the acquired identifier thereof is configured, able or arranged to process. The ultrasound probe 200 may acquire the information regarding at least one of the type of data that may be processed by the diagnostic apparatus and the communication method used by the diagnostic apparatus based on a result of searching for the identifier and determining a stored and mapped type of data is to be used for communications with the diagnostic apparatus to which the probe is connected.
In operation S330, the ultrasound probe 200 determines the type of data that may be processed by the diagnostic apparatus based on the information regarding the diagnostic apparatus.
The diagnostic apparatus having various capabilities and characteristics may process different types of data. Thus, the ultrasound probe 200 determines a step at which the diagnostic apparatus may process data from among a series of processes of acquiring an ultrasound image from the response signal received from the object.
The ultrasound probe 200 may determine that the diagnostic apparatus may process only one type of data or that the diagnostic apparatus may process different types of data.
Essentially, steps S320 and S330 can be condensed, simplified or combined in a single step of determining at least one type of data that a diagnostic apparatus is arranged to process, which diagnostic apparatus is connected to the ultrasound probe, from a plurality of various diagnostic apparatuses, which are connectable to the ultrasound probe.
In operation S340, the ultrasound probe 200 generates transmission data corresponding to the type of data determined in operation S330 from the response signal.
The ultrasound probe 200 according to an embodiment of the present invention generates transmission data corresponding to a type of data that may be processed by the diagnostic apparatus by using a response signal. For example, the type of data may indicate at least one of: data content such as raw data which comprises pixel by pixel full detailed content, MPEG3 streams, MPEG4 streams, and the like; and/or data format for different types of communications (for instance the wireless types of communications of at least one of wireless LAN, Wi-Fi, Bluetooth, Zigbee, WFD, UWB, IrDA, BLE, NFC, Wibro, WiMAX, SWAP, WiGig, and RF communication).
One or more embodiments of the present invention provide a method of outputting data appropriate to the diagnostic apparatus by allowing the ultrasound probe 200 to recognize a signal and/or image processing process that may be performed by the diagnostic apparatus and to have the probe perform a signal and/or image processing process or selected number of steps (including zero or all) in such a process, that may not be performed by the diagnostic apparatus.
That is, the ultrasound probe 200 according to an embodiment of the present invention may selectively output intermediate data generated in an optional processing step from among a series of processes of acquiring the ultrasound image of the object from the response signal received from the object. The intermediate data generated in the processing step selected based on the information regarding the diagnostic apparatus may be the transmission data corresponding to the type of data that may be processed by the diagnostic apparatus.
For example, the ultrasound probe 200 according to an embodiment of the present invention includes basically at least one image processing unit and preferably a plurality of image processing units that process the response signal received from the object in subsequent processing steps. The ultrasound probe 200 may select an image processing mode for the image processing unit and/or the at least one image processing unit from the plurality of image processing unit, necessary for generating the transmission data corresponding to the type of data, which the diagnostic apparatus is arranged to process, which type of data is determined in operation S330. The ultrasound probe 200 may generate the transmission data from the response signal by using the selected at least one of the plurality of image processing units or a mode of image and/or signal processing to be performed by a single more versatile image processing unit. Such a more versatile image processing unit may be a programmable processor, adapted to perform different types of signal and/or image processing for example in subsequent steps or stages, depending on the determined type of data that the diagnostic apparatus is arranged to process subsequently to obtain the ultrasound inage.
In this regard, in an embodiment having a plurality of image processing units, the ultrasound probe 200 may reduce power consumption by disabling the image processing units excluding the selected at least one image processing unit. Alternatively, in an embodiment of the present disclosure having a single (signal or image) processor or other processor, which is arranged to perform several or all of a number of subsequent steps or stages to process the response signal towards the ultrasound image, not all subsequent stages need to be performed by the (image) processor or other processor to provide a readily displayable image. For example, if a diagnostic apparatus is only capable of displaying completely processed image data or ultrasound images, the probe must furnish completely processed image data to the diagnostic apparatus. However, if the diagnostic apparatus is capable of or arranged for processing the received transmission data in a form partly processed by the probe or completely unprocessed by the probe, power consumption of the probe may be reduced, by transmitting to the diagnostic apparatus completely unprocessed or partially processed transmission data, which needs further processing to arrive at image data or the ultrasound image, ready for display on a screen or the like, where such completing processing is performed by the diagnostic apparatus.
An embodiment in which the ultrasound probe 200 generates transmission data of a different type of data according to the diagnostic apparatus will be described in detail with reference to FIG. 4 later.
When one diagnostic apparatus is connected through cables, wires or wirelessly and determined to process various types of data, the ultrasound probe 200 may select one of any number of types of data that may be processed by the diagnostic apparatus and generate transmission data corresponding to the selected type of data.
The ultrasound probe 200 may determine a type of the transmission data in further consideration of a state of the ultrasound probe 200 such as remaining battery charge. In general, the ultrasound probe 200 may have a limited resource compared to the diagnostic apparatus, for example, a limited processing speed of a processor or a limited capacity of a memory. Thus, to increase the processing speed and prevent an overload of the ultrasound probe 200, the ultrasound probe 200 may generate the transmission data in a data type requiring the minimum number of processing steps in the ultrasound probe 200 from among types of data that may be processed by the diagnostic apparatus. Further processing steps to arrive at displayable image data or ultrasound image may then be performed in or by the diagnostic apparatus, thus relieving the load of the probe 200.
In operation S350, the ultrasound probe 200 transmits the transmission data to the diagnostic apparatus.
An example in which the ultrasound probe 200 transmits the transmission data to the diagnostic apparatus wirelessly will now be described. An embodiment of the present invention is not limited to the example. The ultrasound probe 200 may transmit the transmission data by wire.
To receive the transmission data from the ultrasound probe 200, diagnostic apparatuses may use different wired or wireless communication methods. Wireless communication methods used by diagnostic apparatuses may be different according to specifications or peripheral environments of diagnostic apparatuses. Alternatively, wireless communication methods used by diagnostic apparatuses may be different according to bandwidths of types of data that may be processed by diagnostic apparatuses. This is because transmittable and receivable bandwidths are different according to wireless communication methods.
Therefore, the ultrasound probe 200 may determine the wireless communication method used by the diagnostic apparatus based on the information regarding the diagnostic apparatus acquired in operation S320. The ultrasound probe 200 may transmit the transmission data to the diagnostic apparatus by using the determined wireless communication method.
For example, the ultrasound probe 200 may determine at least one of wireless LAN, Wi-Fi, Bluetooth, Zigbee, Wi-Fi Direct (WFD), UWB, infrared data association (IrDA), Bluetooth low energy (BLE), near field communication (NFC), wireless broadband Internet (Wibro), world interoperability for microwave access (WiMAX), shared wireless access protocol (SWAP), wireless gigabit allicance (WiGig), radio frequency (RF) communication, and similar communication methods as the wireless communication method used by the diagnostic apparatus.
The ultrasound probe 200 according to an embodiment of the present invention may include a plurality of communication units that may transmit the transmission data by using different communication methods. The ultrasound probe 200 may select at least one communication unit corresponding to the communication method used by the diagnostic apparatus from the communication units. For example, the ultrasound probe 200 may select at least one communication unit based on a bandwidth of the transmission data that is to be transmitted to the diagnostic apparatus. The ultrasound probe 200 may transmit the transmission data by using the selected at least one communication unit. It is noted here that available communication bandwidth can be detected either by the diagnostic apparatus or the probe and result in selection of a degree of processing starting from the response signal towards resulting images, where only a part of these processing steps may be performed in or by the probe, which would allow a best suited mode of communication, amount of data to be communicated and the like in relation to the bandwidth. Similar other factors or considerations could also be taken into account for this selection, such as types of communication channels by which a probe and a diagnostic apparatus can be connected. Consequently, in addition to a capability of the diagnostic apparatus to continue processing where the probe has stopped and transmitted intermediate results in transmission data to the diagnostic apparatus, other factors like bandwidth can also play a role in determining how far the probe is to proceed in performing a sequence of a number of processing step from the response signal to images, to allow the most suitable transmission of the transmission data and subsequent processing by the diagnostic apparatus. As a further example reference is made here to a type of communication channel, and—in wireless communication—a relation between a theoretical maximum communication speed and an actually achieved communication speed.
For all embodiments of the present disclosure, either explicitly shown and/or described or merely referred to, the probe is capable of all or many of the processing steps, which start on the response signal and progress towards displayable images. However, the probe can detect circumstances like mode of connection, bandwidth, actual transmission speeds, and processing capability of the diagnostic apparatus how many of the processing steps, that the probe is capable of, are actually to be performed up to the point of progress at which the transmission data is formed for transmission to the diagnostic apparatus. By the same token, the diagnostic apparatus may notify the probe of information, to set the level of progress that the probe should perform in a sequence of processing steps, of which the probe is capable, before transmitting the intermediate or final result, in or with the transmission data. Such information may have the form of a command from the diagnostic apparatus, which may even be input by a user, operator or physician.
The ultrasound probe 200 may use a plurality of wireless communication methods to communicate with one diagnostic apparatus. The ultrasound probe 200 may use different wireless communication methods according to characteristics of data that is to be transmitted.
That is, the ultrasound probe 200 may determine a first wireless communication method and a second wireless communication method that are used by the diagnostic apparatus based on the information regarding the diagnostic apparatus. The ultrasound probe 200 may select a first communication unit corresponding to the first wireless communication method and a second communication unit corresponding to the second wireless communication method from among the communication units. The ultrasound probe 200 may transmit the transmission data by using the first communication unit and transmit at least one of state information data of the ultrasound probe 200 and/or receive control data of the diagnostic apparatus by using the second communication unit, or the like.
The state information data of the ultrasound probe 200 may include the remaining battery charge, location information of the ultrasound probe 200, and information about whether the object is scanned by using the ultrasound probe 200. The control data of the diagnostic apparatus may include a control signal relating to an operation of controlling the ultrasound probe 200 in the diagnostic apparatus or a control signal relating to an operation of displaying the ultrasound image generated by using the transmission data received from the ultrasound probe 200 on the screen in such a manner that the ultrasound probe 200 may transceive the ultrasound signal.
FIG. 4 is a block diagram of the ultrasound probe 200 that generates transmission data corresponding to a type of data that may be processed by a diagnostic apparatus according to an embodiment of the present invention.
Referring to FIG. 4, the ultrasound probe 200 according to an embodiment of the present invention may include a plurality of image processing units that process a response signal received from an object. However, the image processing units included in the ultrasound probe 200 according to an embodiment of the present invention are not limited to those shown in FIG. 4. The ultrasound probe 200 may include less or more image processing units than those of FIG. 4.
An acoustic module 411 receives the response signal reflected from the object. The response signal reflected from the object may be an ultrasound signal that is reflected from the object. The acoustic module 411 may include a plurality of transducers. The transducers may vibrate according to transferred electrical signals, generate ultrasound waves that are acoustic energy, process acoustic energy reflected from the object, and generate electrical signals.
A high voltage multiplexer HV mux 413 may sequentially select the transducers of the acoustic module 411. A transmit and receive T/RX analog circuit 415 separates signals acquired by processing a signal used to transmit the ultrasound signal to the object and the response signal received from the object. First and second beam formers 417 and 419 perform focusing on the response signal to determine a reflective characteristic of a tissue of a desired part of the object from the response signal. The first and second beam formers BF1 417 and BF2 419 may be an analog beam former and a digital beam former, respectively.
A mid processor 421 may perform mid processing on signals beam formed by the first and second beam formers 417 and 419. For example, the mid processor 421 may control gains of the beam formed signals. The mid processor 421 may perform phase rotation on each of a plurality of separated regions with respect to predetermined depths of the object according to dynamic frequency variations so as to compensate for frequency variations with respect to the depths of the object. The mid processor 421 may perform low band pass filtering.
A back-end processor 423 may detect envelopes of I component data and Q component data that are output from the mid processor 421. A post processor 425 may perform digital signal processing (DSP) to generate a Doppler (D) mode image and a color (C) mode image. An image generating unit 427 may generate an image that may be displayed on a screen from the processed signal.
As shown in FIG. 4, the diagnostic apparatuses 31, 32, 33, and 34 may process different types of data. That is, the various diagnostic apparatuses may in general be arranged to generate ultrasound image from any intermediate signal or image data, that may be obtained from any of the above described components 413, 415, 417, 419, 421, 423, 425. Hence these components are referred to herein as image processors (413-419, 421-427). Thus, the ultrasound probe 200 according to an embodiment of the present invention provides a method of outputting data in an appropriate form to the diagnostic apparatuses 31, 32, 33, and 34 according to a type of data that may be processed by each of the diagnostic apparatuses 31, 32, 33, and 34 or any one thereof, that is actually connected with the probe at any given time, in such a manner that the ultrasound probe 200 may be used by being connected to various diagnostic apparatuses simultaneously or at different times.
The ultrasound probe 200 may recognize an identifier (ID) of a diagnostic apparatus connected to the ultrasound probe 200 through a diagnostic apparatus ID recognizing unit 430. The ultrasound probe 200 may recognize signal processing that may be performed by the diagnostic apparatus based on the ID of the diagnostic apparatus and the ultrasound probe 200 will then perform signal processing, in particular the initial steps starting from obtaining the response signal, that may not be performed by the diagnostic apparatus, and the transmission data will then be the intermediate processing result or completely finished image data, where the diagnostic apparatus, to which the probe is connected at any one given time, is arranged to process any remaining steps or stages, necessary to arrive at displayable image data or ultrasound image for output on a display or on a screen. Load and power consumption of the probe are thus relieved.
That is, the ultrasound probe 200 may selectively output intermediate data generated in an optional processing step from among a series of subsequent processes from acquiring an ultrasound image of the object from the response signal received from the object and obtaining displayable image data. For example, the probe 200 in combination with the computer 32, the probe will generate the output of the back-end processor, where the diagnostic apparatus is capable of performing the further steps or stages that are necessary for completing the image data or ultrasound image ready for output on a screen or display, in the particular case of the computer 32 in FIG. 4, these steps or stages are those of the post processor 425 and of the image generating unit 427, which functions the probe does not need to perform, when connected with the computer 32.
For example, the first diagnostic apparatus 31 of FIG. 4 in the form of a cart like apparatus, comparable in structure with a conventional cart associated with the probe, may perform all signal processing operations except a beam forming operation. Thus, when the ultrasound probe 200 according to an embodiment of the present invention is connected to the first diagnostic apparatus 31, the ultrasound probe 200 may transmit the signal output from the second beam former 419 to the first diagnostic apparatus 31 as transmission data. In this regard, the ultrasound probe 200 may disable the mid processor 421, the back-end processor 423, the post processor 425, and the image generating unit 427 that perform processing after beam forming.
Unlike the first diagnostic apparatus 31, the fourth diagnostic apparatus 34 of FIG. 4 performs only an image display function without performing an image processing function. Thus, when the ultrasound probe 200 according to an embodiment of the present invention is connected to the fourth diagnostic apparatus 34, the ultrasound probe 200 may transmit the signal output from the image generating unit 427 to the fourth diagnostic apparatus 34 as transmission data.
The ultrasound probe 200 according to an embodiment of the present invention may transmit transmission data to diagnostic apparatuses by using a plurality of wireless communication methods. The ultrasound probe 200 may transmit transmission data to diagnostic apparatuses by using appropriate wireless communication methods according to wireless communication methods used by the diagnostic apparatuses. The ultrasound probe 200 may use a plurality of wireless communication methods to communicate with one diagnostic apparatus. The ultrasound probe 200 may use different communication methods according to a characteristic of data that is to be transmitted.
FIG. 5 is a conceptual diagram for explaining the ultrasound probe 200 that communicates with a diagnostic apparatus 30 by using a plurality of wireless communication methods according to an embodiment of the present invention.
Referring to FIG. 5, the ultrasound probe 200 according to an embodiment of the present invention may transmit transmission data to the diagnostic apparatus 30 at a frequency band of 60 GHz. A plurality of transducers included in the ultrasound probe 200 convert a response signal reflected from an object into an electrical signal. A high bandwidth in several gigabit units is required to wirelessly transmit the electrical signal converted from the response signal having acoustic energy. Furthermore, when the ultrasound probe 200 transmits the transmission data to the diagnostic apparatus 30, no interference with other wireless electronic apparatuses must be generated.
Therefore, the ultrasound probe 200 according to an embodiment of the present invention may transmit the transmission data by using a wireless communication method using millimeter waves (MMW). For example, a wireless communication method following the wireless gigabit alliance (WGA) WiGig standard may be used.
The ultrasound probe 200 may transmit at least one of state information data of the ultrasound probe 200 and control data of the diagnostic apparatus 30 by using Bluetooth separately from the transmission data transmitted at the frequency band of 60 GHz.
