A new display technique for computer-processed digital scans.

Abstract

This article presents a new approach for presenting scintigraphic images. The technique combines the conventional plotting the contour lines and the highlighting, by means of hatching, of the concavities (or convexities) of the 'surface' representative of radioactive distribution. The search for the surface features is achieved generally by the method of normal curvatures. An example with a phantom demonstrates the utility of this representation method.
