PROBLEM TO BE SOLVED: To provide a method and system to measure soft tissue, a contrast medium and a bone in a subject by X-ray transmission imaging.;SOLUTION: In an X-ray detector 3, a plurality of X-ray detecting elements 3a-3d generating a charge by energy applied by X rays incident after transmitting a subject S are arranged in a row on an X-ray incident line such that their distances from an incident end are different from one another, and absorbents 3e, 3f absorbing and attenuating a part of the X rays are disposed at a plurality of points between the detecting elements in the X-ray detecting elements row. The X-ray detector determines the thicknesses of soft tissue, a contrast medium and a bone by thickness operation from ratios of output current values of the plurality of the X-ray detecting elements of the X-ray detector.;COPYRIGHT: (C)2013,JPO&INPIT
