Abstract

Digital angiography is widely considered simply as a method in which images taken at different times are subtracted from each other. This paper presents some techniques which are performed in the frequency domain after the application of the Fourier Transform. Nonselective bypass angiograms and intravenous ventriculograms are taken as examples to show that simple procedures utilizing these techniques exhibit the advantages of improved signal to noise ratio in the subtraction images, reduction of motion artefacts, easy application of phase-synchronous subtraction, integration and quantitative visualization of blood propagation.
