Abstract

A radiographing system includes a radiation detection apparatus that detects radiation that passed through a subject and outputs image data, a spatial statistical processing unit that acquires an average pixel value and a variance value of a predetermined pixel based on the image data and performs a spatial statistical process, a time statistical processing unit that acquires an average pixel value and a variance value in a time-series manner based on a plurality of image data and performs a time statistical process, and a display unit that displays a spatial statistical image based on spatial statistical information or a time statistical image based on time statistical information.
