Patient-specific cardiovascular simulation has become a paradigm in cardiovascular
research and is emerging as a powerful tool in basic, translational and clinical research. In …

Vascular diseases are among the most important public health problems in developed
countries. Given the size and complexity of modern angiographic acquisitions, segmentation …

We present a modeling framework designed for patient-specific computational
hemodynamics to be performed in the context of large-scale studies. The framework takes …

Biological semiflexible polymers and filaments such as collagen, fibronectin, actin,
microtubules, coiled-coil proteins, DNA, siRNA, amyloid fibrils, etc., are ubiquitous in nature …

The invention provides a method and system for performing an image-guided endoscopic
medical procedure. The invention may include registering image-space coordinates of a …

The change in morphology, diameter, branching pattern or tortuosity of retinal blood vessels
is an important indicator of various clinical disorders of the eye and the body. This paper …

The last half century has seen the development of many biological or physical t-ories that
have explicitly or implicitly involved medial descriptions of objects and other spatial entities …

Several geometric active contour models have been proposed for segmentation in computer
vision and image analysis. The essential idea is to evolve a curve (in 2D) or a surface (in …

Access to natural and artificial passages in the body for treatment or investigation for
possible treatment traditionally make use of elongated instruments that are inserted into the …

Various structures in human physiology follow a treelike morphology, which often expresses
complexity at very fine scales. Examples of such structures are intrathoracic airways, retinal …
