CORRECTION INFORMATION GENERATION METHOD AND CORRECTION INFORMATION GENERATION APPARATUS

摘要

A correction information generation method and a correction information generation apparatus enabling easy Flat-Field Correction operation without special accessory equipment are provided. The correction information generation method for performing Flat-Field Correction of X-ray detection sensitivity on a pixel detector, includes the steps of: moving the relative position of a detector 130 with respect to an incident X-ray having a cross-sectional beam shape traversing a detection surface so that the whole of the detection surface is irradiated with the incident X-ray in total time and each of pixels arranged in the moving direction is uniformly irradiated; and generating information for correcting the sensitivity of a pixel based on an intensity value detected for a given energy band of the incident X-ray.
