X-ray angiocardiology

Abstract:

Radiology allows to obtain an x-ray film to part of the human body by its exposure to X-rays. The radiation that passes through the studied object is attenuated according to the density and thickness of the object. The attenuated rays arrive at a receiver that can be the photographic film or an image intensificator that produces an image whose contrast is useful to the medical diagnosis. Angiography is a radiological procedure used to analysis blood flow in any organ of the body. Cardiac angiography to observe the coronary arteries, vascular angiography to study the irrigation of the brain, and ventriculography to observe the ventricular cavity are highlighted in this procedure. In this paper, a set of techniques developed for processing images acquired during cardiac angiography procedures is presented.
