1. A method for processing an image, comprising: identifying one or more surfaces in a three-dimensional image generated from a set of projection data via image processing circuitry of an imaging system; differentially processing the set of projection data based on the one or more surfaces via image processing circuitry of the imaging system, wherein differentially processing comprises dynamically filtering the set of projection data by applying an edge-enhancing filter to those data points in projection data that correspond to attenuation measurements along the ray paths that contribute to the definition of edge features in the reconstructed image set and applying a contrast-enhancing or standard filter to the other data points in the projection data; and reconstructing an enhanced image from the set of processed projection data via image processing circuitry of the imaging system.
