A simple operator-guided alignment technique based on volume-rendered images was developed to register tomographic nuclear medicine studies. For each of two 3-D data sets to be registered, volume-rendered images were generated in three orthogonal projections (x,y,z) using the method of maximum-activity projection. Because manipulation was performed on small 2-D rendered image, feedback was instantaneous. To aid in the visual alignment, difference images and flicker images were displayed. Accurate registration was shown to be achievable in under 10 minutes.
