Image Processors for Digital Angiography Algorithms and Architectures

subject

description

After a period of experimental and clinical development,(1–9) digital processing of angiographic X-ray video image sequences is now routinely applied in clinical and research work. The clinical advantages offered by this approach have been discussed in several reports.(10–12) The primary application is the improved visualization of regions of the heart and circulation opacified by X-ray contrast material during angiographic and angiocardiographic examinations. More complex techniques are being developed for improved functional analysis based on digitized angiograms. Technically, the digital techniques also potentially offer improved means of acquiring, storing, and handling images when compared to present film-based angiography. It is therefore expected that in many applications the film will eventually be replaced by digital photoelectronic methods of X-ray image acquisition, archiving, and communication.(9,13,14)
