Title:
X-RAY CT DEVICE, IMAGE PROCESSING PROGRAM, AND IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2006/028085
Kind Code:
A1
Abstract:
An X-ray CT device includes: an X-ray source for irradiating X-rays to an examinee; an X-ray detector arranged to oppose to the X-ray source for detecting X-rays which have transmitted through the examinee and outputting X-ray image data on the examinee; rotation means for rotating the X-ray source and the X-ray detector by a predetermined angle; spatial displacement amount correction information generation means for calculating a displacement amount of the spatial position of the X-ray source and the X-ray detector and generating spatial displacement amount correction information for subjecting the X-ray image data to the position correction based on the displacement amount; and image reconfiguration means for performing position correction of the X-ray image data according to the spatial displacement amount correction information, performing image reconfiguration calculation according to the X-ray image data after the position correction, and generating the X-ray CT image of the examinee.
