Abstract
A filtering method and apparatus for selectively filtering a gray scale angiographic image volume () that images vascular structures and that also contains extraneous non-vascular contrast is disclosed. A minimum vessel width parameter W() is selected. A maximum vessel width parameter W() is selected. A range of widths () are selected such that each vessel width parameter W() lies between W() and W() inclusive. For each W(), an image I(x,y,z) () is generated that selectively retains imaged vascular structures of diameter W(). The images I(x,y,z) () are combined to form a filtered image I(x,y,z) () that selectively images the vascular structures.
