[Digital subtraction angiography with dynamic color function images].
The authors present for the first time the principles and initial results of a laboratory pilot plant with which parametric colour images can be produced in real time. These images are digital function images of the type originally made widely known by Höhne et al. The colour function images can be produced during conventional digital subtraction angiography (DSA) practically as a sideline, that is to say, with a minimum of time and effort, as a parallel product. Despite the fact that the course of the functional processes can be visualised dynamically, the only feature required is the storage capacity of a single digital TV screen image. Of course, the colour function image is not a substitute for exact quantitative evaluations. However, it does furnish a rapid survey of haemodynamic processes for a multitude of patients in routine diagnosis.
