X-RAY CT APPARATUS

摘要

PROBLEM TO BE SOLVED: To perform a gradational magnification changing of a subject easily in X-ray CT measurement. SOLUTION: Two or more retentive positions (518A-518C) of a container for the subject (550A for example) are prepared in a region of an X-ray irradiation between an X-ray generator 502 which generates an X-ray beam 506 and an X-ray detector which detects the X-ray beam. The container is rotated around a rotation shaft and measured at one of the retentive positions. An image with a high magnification is obtained when the retentive position is near to the X-ray generating member, and an image with a low magnification is obtained when it is far from the X-ray generating member.
