Title:
RADIATION-IMAGING SYSTEM AND CONTROL METHOD THEREOF, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/241248
Kind Code:
A1
Abstract:
The present invention is provided with: a radiation-imaging part 100 that includes a pixel array 110 in which pixels 111 which convert radiation 311 transmitting through an object H into an electrical signal are two-dimensionally arranged; an imaging part 410 that is provided separately from the radiation-imaging part 100, and that captures a plurality of images regarding the motion of the object H at least before radiation imaging is performed by the radiation-imaging part 100; an image calculation unit 420 that performs a calculation process on the plurality of images obtained by the imaging part 410 to calculate information regarding the quantity of the physical motion of the object H; and a control unit 200 that performs control such that the radiation-imaging part 100 transitions to the state (accumulation state) in which the radiation-imaging part 100 is allowed to convert the radiation 311 into an electrical signal and accumulate the electrical signal, on the basis of information regarding an instruction to start exposure with the radiation 311 and information regarding the quantity of the physical motion calculated by the image calculation unit 420.
