PROBLEM TO BE SOLVED: To provide an X-ray examination apparatus capable of properly examining a subject even if the position or posture of the subject, which passes through the space between an X-ray irradiator and an X-ray line sensor, is shifted. SOLUTION: The X-ray examination apparatus is equipped with the X-ray irradiator, the X-ray line sensor, an image processing routine and an examination deciding and processing routine. The X-ray line sensor detects the X rays from the X-ray irradiator. In the image processing routine, a raw image due to X rays is subjected to image processing to form a processed image while the subject is examined on the basis of the processed image in the examination deciding and processing routine. Further, in the image processing routine, a processed image is formed through a process for extracting the boundary lines S11-S14 of the subject and a background (the outside part of the subject) from the raw image. In the examination deciding and processing routine, the inside region of the boundary lines S11-S14 of the processed image is set as a target to perform examination. COPYRIGHT: (C)2005,JPO&NCIPI
