<P>PROBLEM TO BE SOLVED: To provide an X-ray imaging apparatus which shortens a photographing interval of each fluoroscopic image. <P>SOLUTION: The X-ray imaging apparatus 1 for photographing a plurality of fluoroscopic images to create a subtraction image from the difference of each fluoroscopic image includes: an X-ray tube 2 that irradiates a subject with X-rays; an X-ray plane detector 4 that detects the X-rays having penetrated through the subject; and an irradiation start time-calculating unit 9 that calculates a photographing start time of the first image based on the end time of an integral period of the X-ray plane detector 4 in the first image of radiography or the start time of the integral period of the X-ray plane detector 4 in the second image of radiography. <P>COPYRIGHT: (C)2012,JPO&INPIT |
