Abstract

A radiographic imaging apparatus includes a radiation generator which irradiates an object with radiation, a detection unit which detects the radiation generated by the radiation generator and transmitted through the object, thereby shooting a radiographic image, and a control unit which controls radiographic imaging by the radiation generator and the detection unit. The detection unit includes a first connection unit to be used to connect the control unit when used portably, and a second connection unit to be used to connect the control unit when stationarily used on a support portion. The detection unit detects which one of the first connection unit and the second connection unit is used to connect the control unit, and determines a shooting operation based on the detection result.

Claims

1. A radiographic imaging apparatus comprising:

a radiation generator configured to irradiate an object with radiation;

a detection unit configured to detect the radiation generated by the radiation generator and transmitted through the object, thereby shooting a radiographic image; and

a control unit configured to control radiographic imaging by the radiation generator and the detection unit,

the detection unit comprising;

a first connection unit configured to be used to connect the control unit when used portably;

a second connection unit configured to be used to connect the control unit when stationarily used on a support portion;

a connection destination detection unit configured to detect which one of the first connection unit and the second connection unit is used to connect the control unit; and

a determination unit configured to determine a shooting operation based on a detection result of the connection destination detection unit,

wherein upon detecting connection by the first connection unit, the determination unit makes a frame rate of shooting lower than that in connection by the second connection unit.

2. The apparatus according to claim 1, wherein

the first connection unit is provided on a side surface of the detection unit perpendicular to an incident plane of the radiation, and

the second connection unit is provided on a bask surface of the detection unit facing the incident plane of the radiation.

3. The apparatus according to claim 1, wherein the first connection unit and the second connection unit are used for communication with the control unit and use different communication protocols.

4. The apparatus according to claim 1, wherein the first connection unit and the second connection unit include connecting terminals which are used for connection and have different shapes.

5. The apparatus according to claim 1, wherein the determination unit determines a shooting driving method of the detection unit based on communication specifications of a connection unit whose connection is detected by the connection destination detection unit.

6. The apparatus according to claim 1, wherein

the first connection unit is used for wireless communication with the control unit, and

the second connection unit is used for wired communication with the control unit.

7. A control method of a radiographic imaging apparatus including:

a radiation generator configured to irradiate an object with radiation;

a detection unit configured to detect the radiation generated by the radiation generator and transmitted through the object, thereby shooting a radiographic image; and

a control unit configured to control radiographic imaging by the radiation generator and the detection unit, the method comprising;

detecting which one of a first connection unit provided in the detection unit and used to connect the control unit when portably using the detection unit and a second connection unit provided in the detection unit and used to connect the control unit when stationarily using the detection unit on a support portion is used to connect the detection unit to the control unit; and

determining a shooting operation based on a detection result in the detecting which one of the first connection unit and the second connection unit is used to connect the detection unit to the control unit,

wherein upon detecting connection by the first connection unit, a frame rate of shooting is made lower than that in connection by the second connection unit in the determining of the shooting operation.
