Classification: A61B

Abstract:
An X-ray computed tomography apparatus, comprising:a helical data collector configured to collect helical data while at least one of a gantry and a couch is moved by a moving device along a body axial direction of an object on the couch in a state that at least one of the gantry and the couch is tilted, including, an X-ray source configured to generate X-rays, and a detector configured to have detector elements laid out in a plurality of rows along the body axial direction; and a data processor configured to reconstruct an image based on the helical data collected by said helical data collector, including, a shift data generator configured to generate shift data for correcting a deviation of X-ray paths due to a tilt of the couch or the gantry, said shift data being obtained based on an angle of the tilt.
