ABSTRACT:
A filtering method and apparatus for selectively filtering a gray scale angiographic image volume (54) that images vascular structures and that also contains extraneous non-vascular contrast is disclosed. A minimum vessel width parameter Wmin(70) is selected. A maximum vessel width parameter Wmax(132) is selected. A range of widths (66) are selected such that each vessel width parameter Wi(194) lies between Wmin(70) and Wmax(132) inclusive. For each Wi(194), an image Ii(x,y,z) (198) is generated that selectively retains imaged vascular structures of diameter Wi(194). The images Ii(x,y,z) (198) are combined to form a filtered image IF(x,y,z) (64) that selectively images the vascular structures.
