Scattered radiation correction apparatus, scattered radiation correction method, and X-ray imaging apparatus

摘要

PROBLEM TO BE SOLVED: To provide a scattered radiation correction device capable of directly leading out an image obtained by reducing a scattered radiation component from an image obtained by X-ray imaging, while prohibiting effect of scattered radiation correction from being unnatural.SOLUTION: A scattered radiation correction device according to one aspect of this invention performs scattered radiation correction on a projection image obtained by X-ray imaging, by using a correction function y=f(x), where x is a pixel value of the projection image and y is a pixel value after the scattered radiation correction. The correction function is an inverse function of a function obtained by parallel displacement of a logistic function y=α/[1+exp[-&bgr;(x-γ)]] showing a logistic curve.
