Title:
RADIOGRAPHIC IMAGE ANALYSIS APPARATUS AND METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2015043959
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To estimate, in an image analysis apparatus and method, and program, a subject's body thickness distribution by analyzing an image of the subject taken by irradiating the subject with radiation.SOLUTION: A radiographic image analysis method comprises: obtaining a subject's image Ik; obtaining a virtual model M of the subject having a prescribed body thickness distribution; generating a combined image of an estimated primary ray image and an estimated scattered ray image as an estimated image Im which estimate is estimated from a radiographic image to be obtained by radiographing the subject, the estimated primary ray image being obtained by estimating, from the virtual model M, a primary ray image to be obtained by radiographing the virtual model M, and the estimated scattered ray image being obtained by estimating, from the virtual model M, a scattered ray image to be obtained by radiographing the virtual model M; modifying a body thickness distribution of the virtual model M such that the difference between the estimated image Im and the subject's image Ik becomes smaller; and determining the modified body thickness distribution of the virtual model M as the body thickness distribution of the subject.
