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 [...]

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 [...]

Minimally Interactive Knowledge-based Coronary Tracking in CTA using a Minimal Cost Path
No opinion
An algorithm for minimally interactive coronary artery tracking is presented. Tracking ability and accuracy results are demonstrated on 16 images CTA images. First, a region of interest is automatically selected and a denoising filter applied. Then, for each [...]

Carotid Lumen Segmentation Based on Tubular Anisotropy and Contours Without Edges
No opinion
We present a semi-automatic algorithm for Carotid lumen segmentation on CTA images. Our method is based on a variant of the minimal path method that models the vessel as a centerline and boundary. This is done by adding one dimension for the local radius [...]

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 [...]

A Minimal Cost Path and Level Set Evolution Approach for Carotid Bifurcation Segmentation
No opinion
We propose a new approach for semi-automatic segmentation of the carotid bifurcation as part of the Carotid Lumen Segmentation and Stenosis Grading Challenge MICCAI'2009 workshop. Three initial points are provided as input, belonging to the Common, the [...]

Coronary Centerline Extraction Using Multiple Hypothesis Tracking and Minimal Paths
No opinion
This paper describes an interactive approach to the identification of coronary arteries in 3D angiography images. The approach is based on a novel multiple hypothesis tracking methodology which is complemented with a standard minimal path search, and it [...]
