Abstract
A method and apparatus for use with a volumetric computed tomography (CT) scanning system. In accordance with the present invention, the volumetric CT scanning system utilizes an area detector to acquire projection data. The acquired projection data is stored in memory. The projection data corresponding to groups of pixels of the detector is then rebinned to thereby reduce the amount of projection data that will be utilized in performing an initial volumetric reconstruction of the image. The reconstructed image may then be processed to identify particular regions of interest, such as a pathology. If a particular region of interest is identified, all of the projection data corresponding to the region is then used to retrospectively reconstruct a high resolution image of the region of interest. The retrospectively reconstructed high resolution image can then be processed and analyzed to further evaluate the region of interest.
