PROBLEM TO BE SOLVED: To display difference image data by a dual energy method excellent in gradation following the updating of a difference coefficient.
SOLUTION: An image data processing part 8 calculates a reference difference coefficient on the basis of the histogram of first original image data in a high tube voltage imaging mode and second original image data in a low tube voltage imaging mode gathered from an object 150, and generates reference difference image data by the subtraction processing of the first original image data and the second original image data using the reference difference coefficient. Then, on the basis of a window level and a window width calculated from the histogram of the first original image data and the reference difference image data, the window level and window width of the difference image data generated by the subtraction processing of the first original image data and the second original image data to which an optional difference coefficient is applied are estimated, the pixel value of the difference image data is converted on the basis of the obtained window level and window width and it is displayed at a display part 9.
