PROBLEM TO BE SOLVED: To provide a technique for effectively displaying a photoelectric effect image and a Compton effect image in X-ray imaging equipment having a dual energy imaging function.
SOLUTION: This X-ray imaging equipment creates a composite image as an X-ray transmission image to a virtual X-ray source based on the photoelectric effect image and the Compton effect image and displays it on a single screen. This equipment is provided with a spectrum storage means 102 storing information of energy spectrum of the X-rays generated by the virtual X-ray source, and X-ray transmission image calculating means 100 and 101 calculating the X-ray transmission image of a subject relative to the virtual X-ray source based on the energy spectrum stored in the spectrum storage means and a dual energy image.
