## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a radiation imaging control apparatus configured to reduce an operator's load for adjusting protocol information so as to be suitable for a patient for every imaging operation when performing a plurality of radiation imaging operations, and a method for controlling the radiation imaging control apparatus.
2. Description of the Related Art
In recent years, a digital X-ray system has become widespread, which irradiates a flat panel detector (FPD) with X rays from an X-ray generation apparatus, reads the X rays transmitted through a patient using the FPD, and transmits an image to an X-ray imaging control apparatus from the FPD to provide an X-ray imaging image to an operator.
In conventional techniques discussed in Japanese Patent Application Laid-Open Nos. 2002-200062, 2005-110844, and 2006-218142, an X-ray imaging control apparatus transmits protocol information including a radiation generation condition such as intensity of X rays irradiated from an X-ray generation apparatus and an irradiation time to an X-ray generation apparatus previous to an X-ray imaging operation, to arrange the protocol information between the X-ray generation apparatus and an FPD using the protocol information previously set in the X-ray imaging control apparatus.
An operator changes the protocol information in the X-ray generation apparatus, and the X-ray generation apparatus notifies the protocol information to the X-ray imaging control apparatus, which can change the protocol information between the X-ray generation apparatus and the FPD.
When the operator changes the protocol information, the operator finely adjusts the protocol information in consideration of the body type, imaging target region, and target region direction of an imaging patient subjected to the X-ray imaging operation, and performs the X-ray imaging operation using the protocol information suitable for the patient.
However, when the operator transmits the protocol information previously set in the X-ray imaging control apparatus for every X-ray imaging operation to the X-ray generation apparatus previous to the X-ray imaging operation as described above, a reset function acts in a general X-ray imaging apparatus, and a numerical value adjusted by the operator for a first imaging operation is reset for a second imaging operation. Therefore, even when the protocol information in the first imaging operation is the same as that in the second imaging operation, the operator is required to re-perform adjustment.
SUMMARY OF THE INVENTION
According to an aspect of the present invention, a radiation imaging control apparatus configured to control a radiation imaging operation using a radiation generation apparatus in which a radiation generation condition is adjustable by a manual operation includes a setting unit configured to set the radiation generation condition for the radiation imaging operation, a transmission unit configured to transmit the radiation generation condition to the radiation generation apparatus, and a transmission control unit configured to limit transmission of the radiation generation condition by the transmission unit in a case where a radiation imaging operation belonging to the same group as that of the radiation imaging operation is performed.

DESCRIPTION OF THE EMBODIMENTS
First Exemplary Embodiment
FIG. 1 is a block configuration diagram of an X-ray imaging control apparatus in a first exemplary embodiment, and illustrates a range 100 of the X-ray imaging control apparatus.
When an imaging protocol for an imaging object is selected previous to an X-ray imaging operation, a determination unit 101 determines the imaging protocol and communicates the imaging protocol to a protocol information acquisition unit 104.
A protocol information storage unit 102 stores protocol information corresponding to the imaging protocol. The protocol information acquisition unit 104 acquires the protocol information corresponding to the imaging protocol from the protocol information storage unit 102 using the imaging protocol communicated from the determination unit 101, and communicates the protocol information to a transmission unit 103.
The transmission unit 103 receives the protocol information from the protocol information acquisition unit 104, and receives a determination of whether the protocol information should be transmitted from a transmission control unit 111. When the transmission control unit 111 determines that the protocol information should be transmitted, the transmission unit 103 transmits the protocol information acquired from the protocol information acquisition unit 104 to an external X-ray generation apparatus. When the transmission control unit 111 determines that the protocol information should not be transmitted, the transmission unit 103 does not transmit the protocol information to the external X-ray generation apparatus.
When a radiation generation condition is changed by an operator's manual operation in the external X-ray generation apparatus, a reception unit 105 receives the changed protocol information from the external X-ray generation apparatus.
When the transmission control unit 111 receives the request of the determination of whether the protocol information should be transmitted from the transmission unit 103, and the imaging operation is a first imaging operation after the start of examination, the transmission control unit 111 communicates the determination of the transmission to the transmission unit 103. When the imaging operation is not the first imaging operation, the transmission control unit 111 communicates the determination of the non-transmission to the transmission unit 103.
The protocol information includes information required for an imaging operation as described below. Examples thereof include kV/mA/mAs/msec/diaphragm amount as X-ray generation parameters, number of times of completed imaging operations in examination, imaging target region information, target region direction information, imaging group information, update presence/absence information, phototimer position, relative position parameter, position linkage, and window width/window medium value/frequency emphatic parameter as image processing parameters.
FIG. 2 is a flowchart of the X-ray imaging control apparatus in the first exemplary embodiment. FIG. 2 illustrates a process from the determination of the imaging protocol by the determination unit 101 in FIG. 1 to the transmission of the protocol information to the external X-ray generation apparatus by the transmission unit 103. In step S101, the determination unit 101 determines the imaging protocol for use in imaging, and communicates the imaging protocol to the protocol information acquisition unit 104.
In step S102, the protocol information acquisition unit 104 acquires the protocol information based on the imaging protocol from the protocol information storage unit 102 using the imaging protocol received in step S101, and communicates the acquired protocol information to the transmission unit 103.
In step S103, the transmission unit 103 receives the protocol information from the protocol information acquisition unit 104, and receives the determination of whether the protocol information should be transmitted from the transmission control unit 111. When the imaging operation is the first imaging operation after start of examination, the transmission control unit 111 communicates the determination of the transmission. When the imaging operation is not the first imaging operation after start of examination, the transmission control unit 111 communicates the determination of the non-transmission. When the transmission unit 103 receives the determination of the transmission from the transmission control unit 111, the transmission unit 103 transmits the protocol information communicated from the protocol information acquisition unit 104 in step S102 to the external X-ray generation apparatus in step S104, and ends the process. When the transmission unit 103 receives the determination of the non-transmission from the transmission control unit 111, the transmission unit 103 ends the process as it is without transmitting the protocol information to the external X-ray generation apparatus.
Second Exemplary Embodiment
A block configuration diagram in a second exemplary embodiment is the same as that of the first exemplary embodiment.
When the transmission control unit 111 receives the request of the determination of whether the protocol information should be transmitted from the transmission unit 103, and imaging group information in the protocol information and imaging group information in protocol information used for a previous imaging operation in the same examination do not belong to the same group, the transmission control unit 111 communicates the determination of the transmission to the transmission unit 103. When the two pieces of imaging group information belong to the same group, the transmission control unit 111 communicates the determination of the non-transmission to the transmission unit 103. The transmission control unit 111 retains the protocol information acquired from the transmission unit 103 until the next imaging operation in the same examination.
FIG. 3 is a flowchart of an X-ray imaging control apparatus in the second exemplary embodiment. FIG. 3 illustrates a process from the determination of the imaging protocol by the determination unit 101 in FIG. 1 to the transmission of the protocol information to the external X-ray generation apparatus by the transmission unit 103. In step S201, the determination unit 101 determines the imaging protocol for use in imaging, and communicates the imaging protocol to the protocol information acquisition unit 104.
In step S202, the protocol information acquisition unit 104 acquires the protocol information based on the imaging protocol from the protocol information storage unit 102 using the imaging protocol received in step S201, and communicates the acquired protocol information to the transmission unit 103.
In step S203, the transmission unit 103 receives the protocol information from the protocol information acquisition unit 104, and receives a determination of whether the protocol information should be transmitted from the transmission control unit 111. When the imaging group information in the protocol information received from the transmission unit 103 from the protocol information acquisition unit 104 and the imaging group information in protocol information used for a previous imaging operation in the same examination do not belong to the same group, the transmission control unit 111 communicates the determination of the transmission. When the two pieces of imaging group information belong to the same group, the transmission control unit 111 communicates the determination of the non-transmission. When the transmission unit 103 receives the determination of the transmission from the transmission control unit 111, the transmission unit 103 transmits the protocol information communicated from the protocol information acquisition unit 104 in step S202 to the external X-ray generation apparatus in step S204, and ends the process. When the transmission unit 103 receives the determination of the non-transmission from the transmission control unit 111, the transmission unit 103 ends the process as it is without transmitting the protocol information to the external X-ray generation apparatus. The same imaging group information in the present exemplary embodiment includes performing a plurality of imaging operations using one imaging protocol such as a long-length imaging operation. The long-length imaging operation means the following imaging technique. The whole length of a lower limb is imaged, for example, three times because an imaging area is insufficient in one imaging operation when the whole length of the lower limb is imaged as illustrated in FIG. 4, for example. Because the present exemplary embodiment determines the three imaging operations as the same imaging group information, the transmission unit 103 in FIG. 1 transmits the protocol information to the external X-ray generation apparatus for the first imaging operation, and the transmission unit 103 does not transmit the protocol information for the second and third imaging operations.
Third Exemplary Embodiment

In step S303, the transmission unit 103 receives the protocol information from the protocol information acquisition unit 104, and receives a determination of whether the protocol information should be transmitted from the transmission control unit 111. When the imaging target region information in the protocol information received from the transmission unit 103 from the protocol information acquisition unit 104 and the imaging target region information in protocol information used for a previous imaging operation in the same examination do not belong to the same target region, the transmission control unit 111 communicates the determination of the transmission.

When the imaging target region information for the first imaging operation is CHEST, for example, and the imaging target region information for the second imaging operation is CHEST in the present exemplary embodiment, the transmission unit 103 does not transmit the protocol information in FIG. 1. When the imaging target region information for the first imaging operation is CHEST and the imaging target region information for the second imaging operation is ABDOMEN, for example, i.e., the two pieces of imaging target region information do not belong to the same target region, the transmission unit 103 transmits the protocol information to the external X-ray generation apparatus.
