Abstract

Arteriovenous malformations in the brain are abnormal connections between cerebral arteries and veins without the capillary system. They might rupture with  fatal consequences. Their treatment is highly patient-specific and includes careful analysis of  the vessels’ configuration. We present an application that visualizes the blood flow after different combinations of blockages of feeder arteries. In order to convey a detailed  representation of flow in all regions of the vascular structure, we utilized the visual effect graph of the Unity game engine that allows displaying several million particles simultanously. We conducted an informal eval- uation with a clinical expert. He rated our application as beneficial  in addition to the tools used in clinical practice, since the interactive block- age of arteries provides valuable feedback regarding the influence of the blood flow of the remaining arteries.
