Segmentation of Blood Vessels

PhD Qualifying Examination


Title: "Segmentation of Blood Vessels"

Mr. Wai-Kong Law


Abstract:

Clinical assessment of vasculatures is essential for the treatments of
vascular diseases which can be potentially fatal. To facilitate clinical
vessel assessment, there is a growing need of automated vessel
segmentation schemes based on angiographic images, such as Magnetic
Resonance Angiography (MRA), Fluorescein Angiography (FA), 3D-Rotational
Angiography (3DRA), Digital Subtraction Angiography (DSA) and Computed
Tomography (CT).  Various approaches were proposed in the past decade for
the segmentation of vascular structures. The development of these
approaches aims at delivering more accurate and robust segmentation
results. In this survey, these approaches are categorized according to
their assumptions on the shape of blood vessels and their underlying prior
knowledge about the target image modalities.  Analysis of the
formulations, the strengths and the weaknesses of these approaches are
presented. With the advance of imaging techniques, new technical
challenges to vessel segmentation are created. Finally, the future
research directions of segmentation of blood vessels are discussed.
