A method for including redundant data in computed tomography.

M D Silver1.   

Abstract

A method for including redundant data in fan-beam computed tomography (CT) is presented. It is a natural extension of the Parker [Med. Phys. 9, 254-257 (1982)] short-scan approach applied to divergent fan-beam (or cone-beam) data when the data set covers between the minimally complete set of 180 degrees plus fan angle and 360 degrees. A virtual fan angle is introduced whose value is the difference between the angular range of the data collected and 180 degrees. Parker-weights are then applied as if the field-of-view is spanned by the virtual fan angle.
