Here are a few images from an ongoing
research project at the Computer
Science Department at UAH. These are images from our visualization
of the left ventricle of the heart in Gated Blood Pool SPECT data. We have
developed a technique that will automatically extract the left ventricle
and will fit an ellipsoid. The shape and size parameters of the left ventricle
are then extracted and can be used to assess the heart function.
