Abstract
A CT imaging method determines geometric features (information representing geometries) of contact surfaces between markers and an object from tomographic images obtained by imaging the object attached with the markers on its reference surfaces using a CT apparatus, determines from the geometric features a positional relation between a reference coordinate system of the object and a coordinate system of the CT apparatus, and, based on the positional relation, produces tomographic images (bit-map data) of a desired portion of the object.
