Claim One:
1. An X-ray imaging apparatus comprising: a multi X-ray source which includes X-ray targets and a plurality of X-ray focuses to generate X-rays by irradiating the X-ray targets with electron beams, wherein the plurality of X-ray focuses are divided into a plurality of groups; a detector configured to detect X-rays emitted from the multi X-ray source and reached a detection surface of the detector; a change unit configured to change positions of the multi X-ray source and the detector at the same time; an acquisition unit configured to acquire X-ray detection signals from the detector for each irradiation by performing X-ray irradiation a plurality of number of times using the multi X-ray source; and a control unit configured to control the plurality of X-ray focuses of the multi X-ray source by simultaneously driving X-ray focuses belonging to each of the plurality of groups so as to prevent X-rays from interfering with each other on the detection surface of the detector.
