30 January 2012Interactive 3D segmentation by tubular envelope model for the aorta treatment
We propose a novel interactive 3D segmentation approach and geometric model definition called tubular envelope
model. It is conceived to express the shape of tubular objects. The main challenges we have achieved are the
speed and interactivity of the construction. A computer program designed for this task gives the user full control
of the shape and precision, with no significant computational errors.
Six CT (computed tomography) aortic dissection images have been used for the tubular envelopes construction.
Hence, we have proposed a generic parametric model of the aorta for its interactive construction. It leads us to
rapid visualization and navigation inside the artery (rough virtual angioscopy). The low complexity of the model
and the ease of interactive design makes the tubular envelope suitable for aorta segmentation in comparison to
the other segmentation methods. The model accuracy is adjustable by the user according to his requirements;
the time of construction is approved by clinicians.
More generally, the tubular envelope could be used in other applications, e.g. to define a region of interest
for more precise segmentation or feature extraction inside, to develop a parametric model with deformation
capabilities.
