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 [...]

Dose Painting with a Variable Collimator for the Small Animal Radiation Research Platform (SARRP)
No opinion
The goal of radiation treatment is to irradiate cancer cells (i.e., a target region) without destroying adjacent healthy tissue. Thus, it is advantageous to form the beam so that it best approximates the target, thereby reducing the amount of dose absorbed in [...]

Simulation of Active Cardiac Dynamics with Orthotropic Hyperelastic Material Model
Meaningful physical models are important for studying cardiac physiology, such as quantitative assessments of pathology via changes in model parameters, and recovering information from medical images. In order to achieve realistic deformation studies, an [...]

Principal Curves: a Technique for Preliminary Carotid Lumen Segmentation and Stenosis Grading
No opinion
A vessel lumen centerline extraction method is presented. Its preprocessing and initialization for the application to 3D CT angiography (CTA) image volumes are also described. This approach is based upon the theory of principal curves to finding lumen axis. [...]

A semi-automated method for liver tumor segmentation based on 2D region growing with
Liver tumour segmentation from computed tomography (CT) scans is a challenging task. A semi-automatic method based on 2D region growing with knowledge-based constraints is proposed to segment lesions from constituent 2D slices obtained from 3D CT images. [...]
