Title:
RADIOGRAPHIC IMAGE CAPTURING DEVICE, RADIOGRAPHIC IMAGE CAPTURING SYSTEM, RADIOGRAPHIC IMAGE CAPTURING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/105493
Kind Code:
A1
Abstract:
A radiographic image capturing device capable of calculating with a high degree of accuracy an average energy or an average number of photons of radiation using a smaller number of pixel values than in the prior art captures a radiographic image by means of radiation, and is provided with: a determining means for determining a prior probability on the basis of predetermined criteria; an acquiring means for acquiring a pixel value measured from the radiographic image; and a calculating means for calculating at least one of the average energy and the average number of photons of the radiation on the basis of the prior probability and the pixel value.
