METHOD AND PARALLEL PROCESSOR FOR RECONSTITUTING 3D IMAGE OF OBJECT FROM CONICAL BEAM PROJECTION DATA

摘要

PURPOSE: To provide method and device for reconstituting a 3D image from conical beam data and an area component. CONSTITUTION: These method and device are provided for reconstituting a 3D CT image while including ordinary 2D CT reconstitution. By using a 2D reconstituting procedure such as filtered backward projection, for example, for each slice for the value of a 2D projection image in the plane of the slice in order to calculate the 2D image of an object for each slice, the 3D image of the object is reconstituted for each slice.
