Two Point Minimum Cost Path Approach for CTA Coronary Centerline Extraction
No opinion
In this work a minimum cost path approach is adopted to extract coronary artery centerlines from CTA data. The algorithm depends on the manual definition of the start and end point of the vessel. The cost image used in the minimal cost path approach is based [...]

3D Interactive Centerline Extraction
No opinion
This document describes a user-steered method to interactively track centerlines of tubular objects in 3D space. The method is developed as a plug-in of ImageJ using Java language. To evaluate the tracking ability and tracking accuracy, this method has been [...]

Fast Marching Minimal Path Extraction in ITK
starstarstarstarstar
This paper describes the ITK implementation of a minimal path extraction framework based on Fast Marching arrival functions. The method requires the user to provide three inputs: 1. a meaningful speed function to generate an arrival function, 2. path [...]

Flux driven medial curve extraction
starstarstarstarstar
In this document it is described the implementation of the flux driven automatic centerline extraction algorithm proposed by Bouix et al. in 2004. This is based on a skeletonisation algorithm initially proposed by Siddiqi et al. in 2002, using properties of [...]

Segmentation of Carotid Arteries By Graph-Cuts Using Centerline Models
No opinion
In this paper, we present a semi-automtic method for segmenting carotid arteries in contrast enhanced (CE)-CT angiography (CTA) scans. The segmentation algorithm extracts the lumen of carotid arteries between user specfied locations. Specifically, the [...]

Tubular Geodesics using Oriented Flux: An ITK Implementation
starstarstarstarstar
This document describes an ITK implementation of an interactive method for tracing curvilinear structures. The basic tools provided in this framework are an oriented flux-based tubularity measure and a geodesic path tracer that uses the fast marching [...]

Implementation of weighted Dijkstra’s shortest-path algorithm for n-D images
No opinion
This paper describes the ITK implementation of a shortest path extraction algorithm based on graph representation of the image and the Dijkstra shortest path algorithm. The method requires the user to provide two inputs: 1. path information in the form of [...]

Adaptations of MARACAS algorithm to the segmentation of the carotid bifurcation and stenosis quantification in CTA images
No opinion
This paper describes a 3D CTA image segmentation method submitted to the CLS09 contest (Carotid Lumen Segmentation and Stenosis Quantification) held in conjunction with the MICCAI 2009 conference. First, images are denoised to improve image quality and [...]
