Multi X-ray imaging apparatus and control method therefor

A control method for an X-ray imaging apparatus including:

• a multi X-ray source which includes a plurality of X-ray focuses to generate X-rays by irradiating X-ray targets with electron beams;
• a detector which detects X-rays which have been emitted from the multi X-ray source and have reached a detection surface;
• and a moving unit configured to move the multi X-ray source within a plane facing the detection surface, said method comprising:
• an acquisition step of acquiring X-ray detection signals from the detector for each irradiation by causing the multi X-ray source to perform X-ray irradiation a plurality of number of times while shifting the multi X-ray source relative to the detection surface by using the moving unit;
• and
• a generating step of generating an X-ray projection image based on a plurality of X-ray detection signals acquired in the acquisition step.
