PROBLEM TO BE SOLVED: To provide radiographic equipment capable of obtaining a high-quality sectional image. SOLUTION: The radiographic equipment comprises: an X-ray source 122 rotating around a subject 1 to irradiate the subject 1 with X rays at a plurality of irradiation angles; an image generating part 130 for generating electric signals according to the dose of X rays penetrating the subject 1 and generating photography images at the plurality of irradiation angles respectively by amplifying the electric signals; a control part 108 for setting the amplification angle of the electric signals for each photography image based on the irradiation angle of the X-ray source 122; and an image reconstruction part for generating the sectional image of the subject by reconstructing a plurality of photography images. The radiographic equipment may also have a subtraction process part for generating an energy subtraction image by subjecting the first and second sectional images generated with different irradiation energy to the subtraction process.
