Title:
RADIATION IMAGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/005262
Kind Code:
A1
Abstract:
The present invention addresses the issue of providing a radiation imaging system capable of obtaining good image quality. The radiation imaging system has: a detection unit (205) that detects image information and includes a plurality of pixels arranged in a matrix, said pixels converting radiation into electric charge and outputting pixel values; a drive control means (204) that causes image information corresponding to radiation exposure to be output, by causing the plurality of pixels to reset until a signal indicating radiation exposure is input, stopping the reset operation of the plurality of pixels and causing electric charge to accumulate once a signal indicating radiation exposure has been input, then causing the pixel values of the plurality of pixels to be read once the radiation exposure has been completed; a correction coefficient acquisition means (207) that calculates a correction coefficient on the basis of image information output by the detection unit; and an image correction means (208) that corrects the image information output by the detection unit, by using the correction coefficient calculated by the correction coefficient acquisition means.
