A methodology that addresses important issues concerned with the underlying graphical
models designed for surgical simulation, as well as issues related to the real-time interactivity …

The methods presented here have been developed to perform the automated segmentation
of coronary arterial structure from cine sequences of biplanar x-ray angiograms. We …

An expert system (PERFEX) developed for the computer-assisted interpretation of myocardial
perfusion SPECT studies is now becoming widely available. To date, a systematic …

Presents a new method to determine the orientation or pose of the left ventricle (LV) of the
heart from cardiac SPECT (single photon emission computed tomography) data. This …

This paper focuses on a method for generating polyhedra from a set of lattice points, such
as three-dimensional (3D) medical computerized tomography images. The method is based …

Active contour models (commonly called `snakes'') have shown themselves to be a powerful
and flexible paradigm for many problems in image understanding. Active contour models …

Models created independently from nuclear perfusion images of the myocardium and x-ray
angiograms of the coronary arteries are placed in register to produce a unified three- …

A new implementation of the iterative closest point method for automatic registration is
introduced. It is designed to unify three-dimensional models of the coronary artery tree created …

Pose determination of 3-D objects is a topic of active research, particularly in the are of medical
imaging. The determination of the pose or orientation of a 3-D object in a 3-D dataset can …

The accuracy of interpreting tomographic nuclear medicine images of the heart varies
depending on the expertise of the diagnostician. This variability is a problem at some community …
