Abstract:The aim of this bachelor thesis is to improve the evaluation of arteriovenous malformations (AVM) in 4D computed tomography angiography (4D-CTA) using Matlab. For this evaluation anonymised AVM datasets from patients from the UMC St Radboud are loaded into Matlab. With this loaded data an automatic evaluation of the AVM will be developed. The AVM datasets have been made Matlab compatible and afterwards they were cropped. The cropping reduces the size of the data and makes Matlab perform better. Following the blood vessels are segmented using a mask image to filter the surrounding irrelevant tissue. These images of solely blood vessels are aligned and played in a movie where the vascular filling is shown. To continue placing a mark near the nidus to indicate and visualize the AVM can be a valuable progress. Next to this visualization it would be useful to look at navigation for the treatment of an AVM. keywords: AVM, arteriovenous malformation, 4D CTA, 4D computed tomography, Matlab, navigation, DSA, digital subtraction angiography
