Patent ID: 7680242

Claim:
An X-ray examination method using an X-ray examination apparatus including a light receiving part for detecting an X-ray transmitted through an object by X-ray irradiation with a plurality of X-ray sensors, the method comprising the steps of: specifying an examining portion of the object; generating the X-ray by moving, with respect to the plurality of X-ray sensors, an X-ray focal position of an X-ray source to each starting position of X-ray emission set such that the X-ray transmits through the examining portion and enters each of the X-ray sensors; detecting an intensity distribution of the X-ray transmitted through the examining portion at each of the X-ray sensors; and reconstructing image data of the examining portion based on data of the detected intensity distribution, wherein the step of generating the X-ray includes: specifying a plurality of X-ray sensors for detecting the X-ray; setting each starting position on a target surface which is a continuous surface of the X-ray source such that the examining portion is on a straight line from each of the plurality of X-ray sensors to the starting position; and generating the X-ray by changing an irradiation position to apply an electron beam of the X-ray source to each starting position and moving the X-ray focal position, wherein the step of detecting an intensity distribution includes: arranging a rotatable base with the plurality of X-ray sensors on a circumference having a predetermined axis as a center; and rotating the rotatable base about the axis, wherein the X-ray source is a scanning X-ray source.
