Abstract: This X-ray imaging apparatus is equipped with an X-ray tube, a detector for detecting X-rays emitted from the X-ray tube and transmitted through the subject, and an image processing unit for generating an image based on a detection signal output from the detector. The X-ray imaging apparatus is provided with a controller configured to cause X-rays to be emitted such that the distance between the plurality of focal positions of the plurality of electron beams on the inclined surface differs as viewed from the subject's side, depending on the size of the subject, by causing a part of the plurality of electron emitters to emit electron beams.

Abstract: An object of the invention is to provide an X-ray generator having a simple configuration where heat generated in the irradiation window can be prevented from conducting to a desired portion in accordance with the purpose of use, the method of use or the structure of the X-ray tube. In an X-ray generator for releasing X-rays generated by irradiating a target placed in a vacuumed atmosphere within an X-ray tube with an electron beam from an electron source through an irradiation window of the X-ray tube, the irradiation window has thermal anisotropy where the thermal conductivity is different between the direction in which the irradiation window spreads and the direction of the thickness of the irradiation window, and therefore, the thermal conductivity in the direction in which the heat from the irradiation window is desired not to conduct is made relatively smaller.
