An X-ray examination apparatus changes a position of each X-ray sensor by rotating a sensor base, and resets a starting position of X-ray emission that becomes a X-ray focal position so that the X-ray enters each X-ray sensor after the position thereof is changed. A scanning X-ray source deflects an electron beam to easily change the position where the electron beam impinges a target of the X-ray source to an arbitrary location. The irradiating position of the electron beam then can be easily moved according to an accumulated irradiation time on the target. Therefore, maintenance can be performed without interrupting the X-ray examination.
