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 having short calculation time.SOLUTION: A scattered radiation correction device according to this invention performs scattered radiation correction on a measurement image obtained by X-ray imaging. The scattered radiation correction device includes: a normalized ideal value calculation unit for calculating a normalized ideal value, which is a normalized luminance value obtained by the whole X-ray, for each pixel in a measurement image; a scattered radiation component calculation unit for calculating a scattered radiation component of the measurement image for each pixel in the measurement image from the normalized ideal value and a normalized luminance value of the measurement image; and correction processing for removing the scattered radiation component calculated by the scattered radiation component calculation processing from a luminance value of each pixel in the measurement image, for each pixel in the measurement image.
