Radiographic apparatus, radiation detector, and control apparatus and method of radiographic apparatus

A control apparatus of a radiographic system, the radiographic system including a radiation generation apparatus, a radiation detector configured to perform radiographic imaging and an orientation measurement unit configured to perform measurement of orientation of the radiation detector, and a visiting cart configured to carry both the radiation detector and the radiation generation apparatus, the control apparatus comprising:

• a signal output unit configured to output a trigger signal after receiving a stop signal indicating that the visiting cart is at rest or stops but before receiving a completion signal indicating completion of positioning between the radiation detector, which has been taken out of the visiting cart, and the radiation generation apparatus;
• and
• a control unit configured to control the orientation measurement unit to shorten a sampling period of the measurement upon receiving the trigger signal.

A method for controlling a radiographic system, the radiographic system including a radiation generation apparatus, a radiation detector configured to perform radiographic imaging and an orientation measurement unit configured to perform measurement of orientation of the radiation detector, and a visiting cart configured to carry both the radiation detector and the radiation generation apparatus, the method comprising:

• outputting a trigger signal after receiving a stop signal indicating that the visiting cart is at rest or stops but before receiving a completion signal indicating completion of positioning between the radiation detector, which has been taken out of the visiting cart, and the radiation generation apparatus;
• and
• controlling the orientation measurement unit to shorten a sampling period of the measurement upon receiving the trigger signal.
