Paper Abstract

A contrast enhancement digital filtering technique has been explored for improving the visibility of vasculature in nonsubtraction digital angiograms. Experimental results on sample images showed that the average contrast between the vasculature and its surrounding tissue was increased by sixfolds and the signal-to-noise ratio was increased by twofolds. This suggests a great potential of this enhancement filtering technique for digital non-subtraction angiography, bypassing the problem of patient body motion which causes difficulty in image registration in digital subtraction angiography.
