If not, it is determined that there is a communication error, and the display unit 32 is controlled to notify that a communication error has occurred.
- the radiographer receives the identification information of the radiation image detector 5 from the input operation unit 31 of the console 6. input.
- the control unit 29 of the console 6 associates the radiation image detector 5 with the identification information.
- the control unit 29 controls the communication unit 33 to transmit a check signal to the communication unit 24 of the radiation image detector 5. Release based on this check signal.
- the control unit 27 of the ray image detector 5 checks the operation of each drive unit. Here, when the control signal is not received by the control unit 27 or when a response signal is not returned, a communication error has occurred, so that a response is returned to the communication unit 33 of the console 6 for a predetermined time or more.
- the control unit 29 of the console 6 determines that a communication error has occurred, and controls the display unit 32 to notify that a communication error has occurred. Based on the notification, the radiologist takes measures for communication abnormality.
- the radiologist selects the radiological image detector 5 to be used for the imaging on the console 6, and this is input to the input operation unit 31 of the console 6. input.
- This input content is communicated to the communication unit 24 of the selected radiation image detector 5 through the communication unit 33 of the console 6 and input to the control unit 27 as, for example, imaging instruction information.
- the control unit 29 of the console 6 controls the communication unit 33 to transmit a check signal to the communication unit 24 of the radiation image detector 5.
- the control unit 29 detects the presence / absence of a reply signal from the communication unit 24 of the radiation image detector 5 based on the reply instruction, and performs communication if the reply signal has not been input to the communication unit 33 of the console 6 for a predetermined time or longer. It is determined that there is an abnormality, and the display unit 32 is controlled to notify that a communication abnormality has occurred. Based on this notification, the radiologist takes measures against communication errors.
- the control unit 27 of the radiation image detector 5 controls the power consumption of the rechargeable battery 21 on the basis of the imaging instruction information to switch from the standby state to the imaging enabled state. Force to switch Before the switching, the remaining battery level detection unit 40 is controlled so that the remaining battery level 21 is detected. Even when the radiologist directly operates the input operation unit 26 of the radiation image detector 5 and inputs an imaging instruction, the control unit 27 determines whether each of the plurality of driving units is operating based on the imaging instruction. Control the power consumption of the rechargeable battery 21 Then, switch from the standby state to the ready state.
- the control unit 29 of the console 6 causes the communication unit 24 of the radiation image detector 5 to transmit a check signal
- the presence or absence of a reply signal based on the instruction is determined. If the detected signal is not input to the communication unit 33 of the console 6, the display unit 32 is controlled to notify that a communication error has occurred. It is possible to recognize an abnormal communication state. Thus, unnecessary re-imaging can be prevented and the exposure dose to the patient can be reduced.
- the radiation image detector 5 is used in various radiographing rooms, the corresponding console 6 changes whenever the radiographing room changes, and it is necessary to check whether communication is normally performed each time. If it is in the form, a communication check is performed when the correspondence of the console 6 is switched, and as a result, erroneous photographing can be prevented.
- control unit 29 of the console 6 When the control unit 29 of the console 6 is associated with the radiation image detector 5, the control unit 29 of the console 6 controls the communication unit 33 of the console 6 to transmit a check signal to the communication unit 24 of the radiation image detector 5. Therefore, the communication state can be checked immediately after the association is made.
- control unit 29 of the console 6 transmits an imaging instruction signal to the radiation image detector 5
- the control unit 29 of the console 6 is controlled to send a check signal to the radiation image detector 5 Because it is sent to the communication unit 24, the communication status can be checked before shooting.
- the timing to check is not limited to the timing of this embodiment. It is also possible to check at some timing (such as a signal from console 6) or at regular intervals.
- a charging device such as a cradle is used to charge the rechargeable battery 21, but a power supply cord is connected to the terminal of the radiation image detector.
- charging may be performed by receiving power from an external power source.
- the battery It is possible to charge the battery with the battery removed from the radiation image detector.
- reporting part which concerns on this invention was illustrated and demonstrated, the alerting
- the radiographic imaging system of the present invention is useful for radiographic imaging using a force-set type radiographic image detector, and in particular, radiographic imaging using a radiographic image detector moved to various locations. It is suitable for use when performing.
