Vascular Segmentation of Head Phase-Contrast Magnetic Resonance Angiograms using Grayscale and Shape Features

In the process of clinical diagnosis, the maximum intensity projection (MIP) [1] of computed tomography angiography (CTA) or magnetic resonance angiography (MRA) is often utilized for the diagnosis and treatment of vascular diseases. However, this technique cannot truly reflect the vascular structure in 3D space. Given that blood vessels and non-vascular tissues are present in angiograms, the segmentation of blood vessels from the dataset is the basis of quantitative diagnosis and treatment of vascular diseases [2,3].
