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 in medicine to observe the inside of an object, detect a foreign material, and assess an injury.

Ultrasound systems have higher stabilities 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 are widely used along with other medical image diagnostic apparatuses.

Ultrasound diagnostic apparatuses generate an ultrasound image by using ultrasonic image data acquired from an ultrasound probe, and display the generated ultrasound image on a screen to provide the ultrasound image to a user. The ultrasound diagnostic apparatuses may include a control panel for controlling an ultrasound system and setting various functions.

In general, a plurality of functional keys for receiving user input, and an input unit such as a keyboard, are mounted on a control panel of an ultrasound diagnostic apparatus.

The control signal transmitted to the ultrasound probe200may be a signal controlling the ultrasound probe200to transmit and/or receive an ultrasound signal to and/or from the object and to acquire ultrasound image data of the object.

For convenience of understanding, an exemplary case where the ultrasound probe200includes a proximity sensor, a microphone, a touch sensor, and a camera, as shown inFIG. 4, will be described below. It is understood that the exemplary embodiments are not limited to this exemplary case.

FIG. 4is a diagram of the ultrasound probe200including a plurality of sensors, according to an exemplary embodiment.

The ultrasound probe200may include a button for activating or deactivating the microphone208in order to sense sound for a predetermined period desired by the user. Also, the ultrasound probe200may acquire sound data set only when the sound is equal to or greater than a predetermined volume or is in a predetermined dB range as the patient information, in order to sense the sound within a predetermined time period desired by the user.

The ultrasound diagnostic apparatus100senses whether the user contacts the ultrasound probe200by using the touch sensor206to acquire information about whether the ultrasound probe200is in a usage state. The proximity sensor or the touch sensor may include an illuminance sensor for sensing light.

Also, the ultrasound diagnostic apparatus100may acquire data sets about gestures of the user's hand holding the ultrasound probe200, by using the touch sensor206.

FIGS. 5A and 5Bare diagrams illustrating the data sets acquired according to the sensing result of the touch sensor in the ultrasound probe200, according to an exemplary embodiment.

For example, the ultrasound diagnostic apparatus100may determine a gesture of the user as shown inFIG. 5Ato be “gesture 1”. Specifically, if the ultrasound probe200senses five fingers of the user and then senses that an index finger of the user is detached and attached again, the ultrasound probe200may generate a data set indicating “gesture 1” according to the sensing result. The ultrasound probe200may transmit the data set indicating “gesture 1”, which is acquired by the sensing result of the touch sensor206, to the ultrasound diagnostic apparatus100.

Also, the ultrasound diagnostic apparatus100may determine a gesture of the user shown inFIG. 5Bto be “gesture 2”. Specifically, if five fingers of the user are sensed, the second finger is not sensed and then sensed again, and within a predetermined time, the second finger is not sensed and then sensed again, the ultrasound probe200may generate a data set indicating “gesture 2” according to the sensing result. The ultrasound probe200may transmit the data set indicating “gesture 2”, which is acquired according to the sensing result of the touch sensor206, to the ultrasound diagnostic apparatus100.

The ultrasound diagnostic apparatus100may acquire an image data set, that is, a picture, as the patient information, by using the camera212. The ultrasound probe200may include a button for activating or deactivating the camera212in order to acquire the image data set for a predetermined time period desired by the user.

The ultrasound diagnostic apparatus100according to the present exemplary embodiment may perform predetermined operations corresponding to the combinations of the plurality of data sets acquired by the plurality of sensors.

As shown in the following table 1, the ultrasound diagnostic apparatus100may store the combinations of the plurality of data sets acquired by the plurality of sensors201,202and203and the operations performed by the ultrasound diagnostic apparatus100after mapping the data sets and the operations with each other.

The ultrasound diagnostic apparatus100may acquire the plurality of data sets corresponding to the sensing results of the plurality of sensors, from the signal transmitted from the ultrasound probe200.

The ultrasound diagnostic apparatus100may classify whether the plurality of data sets acquired from the ultrasound probe200will be used as the patient information or information for controlling the ultrasound probe200, based on the combination of the plurality of data sets.

For example, a case where the ultrasound diagnostic apparatus100acquires a plurality of data sets including information [scanning, microphone off, gesture 1, camera off] from the signal transmitted from the ultrasound probe200is assumed. In this case, the ultrasound diagnostic apparatus100may determine that the plurality of data sets will be used as the information for controlling the ultrasound probe200, based on the combination of the plurality of data sets. The ultrasound diagnostic apparatus100searches for the operation corresponding to the combination of the acquired plurality of data sets in Table 1, and may perform an operation identified by the searching. Referring to Table 1, the ultrasound diagnostic apparatus100may transmit a control signal to the ultrasound probe200so as to freeze or unfreeze the ultrasound probe200. The operation of freezing or unfreezing the ultrasound probe200may denote stopping or restarting the operation of acquiring the ultrasound image data by transmitting and/or receiving the ultrasound signal to and/or from the object. In particular, when the five fingers of the user are all sensed by the touch sensor, the ultrasound diagnostic apparatus100determines that the user starts manipulation of the ultrasound probe200, and then, may enable the ultrasound probe200to transmit and/or receive the ultrasound signal. In addition, when it is determined that the user's gesture is “gesture 1”, the ultrasound diagnostic apparatus100stops the scanning operation of the ultrasound probe200so as to stop the operations of transmitting and/or receiving the ultrasound signal by the ultrasound probe200.

As another example, when the ultrasound diagnostic apparatus100acquires a plurality of data sets including information [no scanning, microphone off, gesture 1, camera on] from the signal transmitted from the ultrasound probe200, the ultrasound diagnostic apparatus100may store the picture acquired by using the camera as patient information based on the combination of the plurality of data sets.

As another example, when the ultrasound diagnostic apparatus100acquires a plurality of data sets including information [no scanning, microphone on, gesture 2, camera off] from the signal transmitted from the ultrasound probe200, the ultrasound diagnostic apparatus100may store voice data acquired by using the microphone as the patient information based on the combination of the plurality of data sets. The voice data acquired by the microphone may include voice data of the user recording status of the patient and a diagnosis.

As another example, when the ultrasound diagnostic apparatus100acquires a plurality of data sets including information [scanning, microphone on, gesture 2, camera off] from the signal transmitted from the ultrasound probe200, the ultrasound diagnostic apparatus100may determine that the plurality of data sets will be used as the information for controlling the ultrasound probe200based on the combination of the plurality of data sets. The ultrasound diagnostic apparatus100searches Table 1 for an operation corresponding to the combination of the plurality of data sets, and may perform an operation identified by the searching. Referring to Table 1, the ultrasound diagnostic apparatus100may transmit a control signal for controlling the ultrasound probe200based on the acquired voice data. For example, the ultrasound diagnostic apparatus100may determine the meaning of the voice command of the user by analyzing the voice data, and may transmit a control signal corresponding to the voice command of the user to the ultrasound probe200.
