Abstract
A multi X-ray generating apparatus which has a plurality of electron sources arranged two-dimensionally and targets arranged at positions opposite to the electron sources includes a multi electron source which includes a plurality of electron sources and outputs electrons from driven electron sources by selectively driving a plurality of electron sources in accordance with supplied driving signals, and a target unit which includes a plurality of targets which generate X-rays in accordance with irradiation of electrons output from the multi electron source and outputs X-rays with different radiation qualities in accordance with the generation locations of X-rays. The generation locations and radiation qualities of X-rays from the target unit are controlled by selectively driving the electron sources of the multi electron source.
