Representation of the path of a non-disintegrating capsule in the gastrointestinal tract using external scintigraphy and computer graphics.

The intestinal transit rate of a single non-disintegrating object has been measured using gamma scintigraphy. Using computer graphics, a three-dimensional visualization of the data has been developed. The display enables viewing from any angle and should be of value in assessing the effect of variables on the transit of pharmaceuticals and other materials.
