The method of functional imaging is applied to x-ray angiograms. Functional images are generated by inserting at each point of an x-ray image a computed grey or colour value proportional to a dynamic parameter (such as blood velocity) instead of the recorded x-ray absorption value. For this purpose a new system for angiographic image processing has been(More)
A new computer-aided x-ray technique is presented which, unlike conventional cine- or video-densitometry, allows a high-resolution quantitative display of the parameters of renal blood flow as so-called 'functional images'. The parameters include blood flow velocity and local perfusion of the kidney. This technique, which we call computer angiography, has(More)
