In radiation therapy treatment planning, physicians need to understand the
three-dimensional distribution of radiation dose in the fullest possible context
of the patient anatomy. There are typically many superimposed surfaces
in this data whose 3D shapes and locations must be understood in relation to
To facilitate an immediate understanding of the 3D location of the
relevant soft tissue structures indicated by the skin surface, without unduly
obscuring the visibility of the underlying tumor and dose surface, I
developed a method for automatically highlighting the locations of the valley
and ridge lines that are central to the understanding of the surface shape.
