The human brain has high nutrition and oxygen demand and is critically dependent on a well-functioning blood supply. It is supplied through an arterial circulatory system, the so-called Circle of Willis (CoW). Many cerebrovascular diseases are related to dysfunctions in this vasculature. A disturbance can lead to a medical emergency, the stroke. A patient with suspected narrowing or blockage of blood vessels will be examined by the radiologist via magnetic resonance angiography (MRA).
These MRA sequences are detailed images of the vasculature in the brain. Currently a radiologist makes the diagnosis based on these sequences by viewing slice by slice. There are no advanced visualization techniques involved. This work’s goal is to automate certain steps in his diagnosis process and provide some sort of visual indication of suspicious areas.
