RADIOGRAPHIC IMAGING SYSTEM, INFORMATION PROCESSOR FOR RADIOLOGICAL IMAGE, INFORMATION PROCESSING METHOD FOR RADIOLOGICAL IMAGE AND PROGRAM THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a technology that makes it possible to acquire information capable of separating two substances constituting a radiological image of a subject without executing imaging with radiation energy changed.SOLUTION: A radiographic imaging system has: a detector that includes multiple pixels for acquiring a pixel value corresponding to a radiation ray entering after going through a subject; and an information processing part for executing processing of estimating information about thickness and density of substances constituting the subject, by making a calculation using a pixel value of an arbitrary pixel of the plurality of pixels and an average value of radiation quantum energy of the arbitrary pixel calculated on the basis of the pixel value of the arbitrary pixel.SELECTED DRAWING: Figure 1
