Voxel based Monte Carlo calculations of nuclear medicine images and applied variance reduction techniques are applied to decrease the time required to compute a given number of events at the detector. Stratification and two implementations of forced detection variance reduction techniques are compared to ”brute force” calculations for their efficiency speed-ups in this heterogeneous geometry. Simulated clinical images of the liver are shown.

Reconstruction of 3-D branching structures,mented), it becomes possible to refine portions of the structure that previously were considered ambiguous. Simulations were performed using a mathematically defined test object having 10 branches. In every case, the true structure was able to be distinguished from the artifacts using as few as three projections.

Bayesian reconstruction of functional images using registered anatomical images as priors,s in the vicinity of the significant anatomical boundaries. Simulations on anatomically derived mathematical phantoms are presented. The reconstructions are greatly improved when the prior information is used.

Automatic detection of brain contours in MRI data sets,he third dimension. A summary of results of testing the algorithm on 23 test data sets is presented, with a discussion of potential for clinical application and generalization to other problems, and of limitations of the technique.
