PROBLEM TO BE SOLVED: To provide an X-ray image processing device that performs a test for highly reliable quality control for an X-ray imaging device.SOLUTION: An X-ray image processing device acquires an image created by a sensor that detects an X-ray irradiated from a radiation source, creates an evaluation value for evaluating the quality of the image based on the acquired image, determines a result of an evaluation for the quality of the image based on the created evaluation value, and displays the determined evaluation result. In accordance with a plurality of different detection modes for detecting the X-ray irradiation set for the sensor, the X-ray image processing device performs different processing.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT
