Title:
APPARATUS AND METHOD FOR CORRELATING FIRST AND SECOND 3D IMAGES OF TUBULAR OBJECT
Document Type and Number:
WIPO Patent Application WO2006095309
Kind Code:
A3
Abstract:
A computer tomography (CT) imaging apparatus (2) for correlating images of the colon in prone and supine positions is disclosed. The apparatus comprises pairs of x-ray sources (6) and detectors (8) for generating 3D image data representing at least one first location on the colon wall in the prone or supine position, and for generating 3D image data representing a plurality of locations along the teniae coli extending along the colon wall in that position. The sources and detectors also generate 3D image data representing the same locations along the teniae coli in the other of the prone or supine position. A computer (16) contains a processor (20) for determining a location in the second scanned image corresponding to the first location in the first scanned image.
