Abstract

When correcting for artifacts on an attenuation map caused by an artifact source in a computed tomography image, nuclear images are reconstructed two or more times, each time using a different correction technique or uncorrected attenuation data. Corresponding voxels in the reconstructed images are compared to identify local areas that change, i.e., are fragile and therefore low-confidence, and areas that do not vary or exhibit little variance among the plurality of reconstructed images and are thus accorded a higher confidence. The reconstructed nuclear image is overlaid with color encoding indicative of the amount of confidence accorded to each voxel value obtained by attenuation-corrected tomographic reconstruction.
