Method and apparatus for detecting of complete radon data for the exact creation of a three-dimensional ct - image of a part of a radiation of a conical source occupied object

摘要

A method and apparatus for exact three dimensional reconstruction of the image of a portion of interest of an object in the field of view of a cone beam source is disclosed, whereby unwanted Radon data are selectively disgarded avoiding undue corruption of the imaging process and missing Radon data that would otherwise be lost are selectively recovered. This is accomplished by ensuring the acquisition of a complete set of Radon data through proper choice of scanning configuration, then selectively partitioning and manipulating the acquired data to image only the select portion of interest of the object.
