Computer angiography: a new tool for x-ray functional diagnostics.
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 developed. First results show that the method which we have called Computer Angiography is a tool to extract more information about the blood dynamics in organs in an easier and faster way than with the conventional angiographic technique.
