Functional imaging of blood flow velocity amd myocardial perfusion using the Fourier transform parameter

In the past, the radiology of the cardiovascular system has consisted of angiographic investigations which only demonstrate morphology. The introduction of digital techniques into radiology has made possible the demonstration of pure morphology and beyond that, calculations which provide functional information. We demonstrate functional images which, by using Fourier transformations, provide information on blood flow and organ perfusion. In this way, it is possible to obtain important additional diagnostic information concerning the cardiovascular system, without imposing any further stress on the patient.
