Paper Abstract

This paper proposes a registration method of the colon taken in two positions of CT images. CT colonographybased colon diagnosis using 3D CT images taken in supine and prone positions is time-consuming because a physician has to refer to many CT images for the diagnosis of a patient. Automated synchronization of the observing areas in the two positions is required to reduce the load on physicians. This paper proposes a novel registration method of the colon in two positions to synchronize the observing areas. The registration process utilizes the sharp curved points of the colon centerlines and haustral folds as landmarks. A dynamic programming technique finds correspondence between the haustral fold landmarks in the two positions. The experimental results using six pairs of CT images showed that the mean registration error was 4.70 [mm].
