Title:
RADIATION IMAGING SYSTEM, IMAGING CONTROL DEVICE, RADIATION IMAGING DEVICE, RADIATION IMAGING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/230114
Kind Code:
A1
Abstract:
This radiation imaging system has a radiation imaging device that includes dose detection pixels for detecting the dose of radiation emitted from a radiation source, and an imaging control device that controls the radiation imaging device. Prior to radiation imaging, the imaging control device specifies the position of a dose detection pixel in a region of interest for calculating a dose index value of a radiation image, determines a threshold value that corresponds to the position of the dose detection pixel, and transmits the threshold value and the position of the dose detection pixel to the radiation imaging device. The radiation imaging device sets the threshold value and the position of the dose detection pixel in the region of interest transmitted from the imaging control device, and performs imaging on the basis of the setting.
