Abstract
The present invention, in one aspect, is a method for producing an enhanced tomographic image of an object. The method includes steps of obtaining fan beam projection data of the object from a tomographic scan; rebinning the fan beam projection data into a quantity of parallel projection data points; applying interpolation to the quantity of parallel projection data points to increase the quantity of parallel projection data points; and generating a tomographic image from the increased quantity of parallel projection data points.
