Modeling spectral changes to visualize embedded volume structures for medical image data

Abstract

When a volume structure is embedded in another volume structure, it is difficult to see the inner structure without destroying the view on the outer structure. We present a solution by letting the volume structures scatter light with a different wavelengths. The outer volume structure only absorbs light scattered by the structure itself and does not absorb the light scattered by the inner structure, by which the inner structure is visible without destroying the view on the outer structure. Examples are shown of vascular imaging and CT imaging.
