Abstract
A radiation image capturing system includes a plurality of radiation image capturing apparatuses that each performs an image capturing operation to capture a radiation image based on radiation emitted from a radiation generating apparatus and transmitted through an object, a control apparatus that communicates with the plurality of radiation image capturing apparatuses, a calculation unit that calculates information about similarity between the radiation image and a reference image, and an image acquisition unit that acquires the radiation image from the radiation image capturing apparatus selected from the plurality of radiation image capturing apparatuses based on the information about similarity.
Claims14
A radiation image capturing system comprising:
- a plurality of radiation image capturing apparatuses each configured to perform an image capturing operation to capture a radiation image based on radiation emitted from a radiation generating apparatus and transmitted through an object, the plurality of radiation image capturing apparatuses each including a plurality of pixels arranged in a two-dimensional array, a drive circuit configured to drive the plurality of pixels, and an image storage unit configured to store the radiation image based on the signal read from the plurality of pixels driven by the drive unit;
- a control apparatus configured to communicate with the plurality of radiation image capturing apparatuses;
- a calculation unit configured to calculate information about similarity between the radiation image and a reference image;
- and
- an image acquisition unit configured to acquire a radiation image from a radiation image capturing apparatus selected from the plurality of radiation image capturing apparatuses based on the information about similarity.
