A system that adjusts the frequently used standard {CA} dose for individual patients based on their clinical parameters can be useful. As basis the quality of the image contrast in {CTA} volumes has to be determined, especially to recognize excessive contrast induced by {CA} overdosing. However, a manual assessment with a {ROI}-based image contrast classification is a time-consuming step in everyday clinical practice.},
