Abstract

The CT angiography (CTA) method is a mini-invasive diagnostic method for displaying blood vessels using computer tomography (CT) and the concurrent application of a contrast agent (CA). This article focuses on assessing brain perfusion in time based on a 4D reconstruction using one of the image transformation methods—morphing. The proposed methodology is very important for clinical practise. On the base this approach we are able to perform reconstruction of 4D CTA brain perfusion without using contrast substance. It is main difference against conventional procedures which are used during the examination. Patient is not exposed by contrast substance.
