A Deformable Vessel Model with Single Point Initialization for Segmentation, Quantification and Visualization of Blood Vessels in 3D MRA |
Abstract | ||
|---|---|---|
We deal with image segmentation applied to three-dimensional (3D) analysis of of vascular morphology in magnetic resonance
angiography (MRA) images. The main goal of our work is to develop a fast and reliable method for stenosis quantification.
The first step towards this purpose is the extraction of the vessel axis by an expansible skeleton method. Vessel boundaries
are then detected in the planes locally orthogonal to the centerline using an improved active contour. Finally, area measurements
based on the resulting contours allow the calculation of stenosis parameters. The expansible nature of the skeleton associated
with a single point initialization of the active contour allows overcoming some limitations of traditional deformable models.
As a result, the algorithm performs well even for severe stenosis and significant vessel curvatures. Experimental results
are presented in 3D phantom images as well as in real images of patients.
