A patch-based framework for new ITK functionality: Joint fusion, denoising, and non-local super-resolution
No opinion
In an earlier Insight Journal article, we introduced an ITK implementation of the adaptive patch-based image denoising algorithm described in [3]. We follow-up up that offering with a generalized non-local, patch-based ITK class framework and a refactored [...]

N-Dimensional Phase Unwrapping
No opinion
Although phase data can take on any value, it is generally only possible to measure phase as a principle value, i.e., wrapped within the range (-pi,pi]. Determining the unwrapped phase from its principle value is a topic of considerable interest in magnetic [...]

Model-based left ventricle segmentation in 3D ultrasound using phase image
No opinion
In this paper, we propose a semi-automatic method for left ventricle segmentation. The proposed method utilizes a multi-scale quadrature filter method to enhance the 3D volume, followed by a model-based level set method to segment the endocardial surface of [...]

Improvements in SlicerRT, the radiation therapy research toolkit for 3D Slicer
No opinion
Purpose: Recent years have seen growing interest in adaptive radiation therapy (RT), but the existing software tools are not ideal for research use, as they are either expensive and closed proprietary applications or free open-source packages with limited [...]

DICOM Spatial Transform IO in the Insight Toolkit
No opinion
This document describes a module that extends the Insight Toolkit, ITK, which reads DICOM Spatial Rogistration Object files in itk::Transform's. Currently, DICOM files are read by applying the DCMTK library as a backend. An itk::DCMTKTransformIO class can be [...]

Fully automatic brain segmentation using model-guided level sets and skeleton-based models
No opinion
A fully automatic brain segmentation method is presented. First the skull is stripped using a model-based level set on T1-weighted inversion recovery images, then the brain ventricles and basal ganglia are segmented using the same method on T1-weighted [...]

Radial Thickness Calculation and Visualization for Volumetric Layers
starstarstarstarstar
Volumetric layers often encountered in medical image analysis are characterized by double and nested bounding surfaces. The thickness of a volumetric layer at a point on the bounding surface is the distance from that point to the opposite surface. There exist [...]

Semi-automatic Segmentation of 3D Liver Tumors from CT Scans Using Voxel Classification and Propagational Learning
starstarstarstarstar
A semi-automatic scheme was developed for the segmentation of 3D liver tumors from computed tomography (CT) images. First a support vector machine (SVM) classifier was trained to extract tumor region from one single 2D slice in the intermediate part of a [...]

Semi-automatic Segmentation of Liver Tumors from CT Scans Using Bayesian Rule-based 3D Region Growing
starstarstarstarstar
Automatic segmentation of liver tumorous regions often fails due to high noise and large variance of tumors. In this work, a semi-automatic algorithm is proposed to segment liver tumors from computed tomography (CT) images. To cope with the variance of [...]

An Automatic Seeding Method For Coronary Artery Segmentation and Skeletonization in CTA
No opinion
An automatic seeding method for coronary artery segmentation and skeletonization is presented. The new method includes automatic removal of the rib cage, tracing of the ascending aorta and initial planting of seeds for the coronary arteries. The automatic [...]

A semi-automated method for liver tumor segmentation based on 2D region growing with
starstarstarstarstar
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. [...]

Simulation of Active Cardiac Dynamics with Orthotropic Hyperelastic Material Model
starstarstarstarstar
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 [...]

Cumulative Gaussian Curve Fitter for Boundary Parameterization
starstarstarstarstar
We have previously developed an algorithm for locating boundaries in an image with sub-pixel resolution, as well as estimating boundary width and image intensity within the adjoining objects. The algorithm operates by finding the parameters of a cumulative [...]

Real-Time Ultrasound Image Analysis for the Insight Toolkit
starstarstarstarstar
We have successfully created a software environment in which ultrasound data can be manipulated by, ITK (the Insight Tool-Kit), in real-time. We were able to access each frame generated within the resident computer of a TerasonTM Ultrasound Machine, convert [...]

MORPHIAS: Molecular Phenotyping Image Analysis System
starstarstarstarstar
Visualizing metabolic phenotypes, tracking phenotype dynamics, and screening molecular interventions all require comprehensive, quantitative measures of micromolecular patterns across cell classes. In this project we develop an easy-to-use interface that [...]
