Abstract:
A method is provided for processing an image. The method comprises identifying one or more contours or surfaces in a two-dimensional or three-dimensional image generated from a set of projection data. The set of projection data is differentially processed based on the identification of those data points that largely define one or more contours or surfaces. An enhanced image set is reconstructed from the set of processed projection data.
