Abstract

A plurality of viewpoints are set in a blood vessel included in an original image obtained in such a way that a plurality of CT images are stacked. The viewpoints are manually or automatically set along the blood vessel in the central projection method. Next, a curved surface including the viewpoints (composed of straight lines intersecting the viewpoints) is set. Then, the original image is cut along the curved surface to construct a sectional image of the original image including a sectional image of the blood vessel, and the constructed sectional image is displayed. The displayed sectional image is a longitudinal sectional image of the blood vessel. Therefore, a longitudinal sectional image of an object such as a blood vessel and an intestine cut along a curved surface along the object can be easily constructed.
