Real-time Tracking of the Left Ventricle in 3D Ultrasound Using Kalman Filter and Mean Value Coordinates
No opinion
A method for real-time automatic tracking of the left ventricle (LV) in 3D ultrasound is presented. A mesh model of the LV is deformed using mean value coordinates enabling large variations. Kalman filtering and edge detection is used to track the mesh in [...]

Left Ventricle Segmentation in Cardiac Ultrasound Using Hough-Forests With Implicit Shape and Appearance Priors
No opinion
We propose a learning based approach to perform automatic segmentation of the left ventricle in 3D cardiac ultrasound images. The segmentation contour is estimated through the use of a variant of Hough forests whose object localization capabilities are [...]

Learning Shape Representations for Multi-Atlas Endocardium Segmentation in 3D Echo Images
No opinion
As part of the CETUS challenge, we present a multi-atlas segmentation framework to delineate the left-ventricle endocardium in echocardiographic images. To increase the robustness of the registration step, we introduce a speckle reduction step and a new shape [...]

Endocardial 3D Ultrasound Segmentation using Autocontext Random Forests
No opinion
In this paper, we present the use of a generic image segmentation method, namely a succession of Random Forest classifiers in an autocontext framework, for the MICCAI 2014 Challenge on Endocardial 3D Ultrasound Segmentation (CETUS). The proposed method [...]

Endocardial Segmentation using Structured Random Forests in 3D Echocardiography
No opinion
Segmentation of the left ventricle endocardium in 3D echocardiography is a critical step for the diagnosis of heart disease. Although recent work has shown effective endocardial edge detection, these techniques still preserve spurious anatomical edge [...]

Real-Time Ultrasound Image Analysis for the Insight Toolkit
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 [...]

CustusX: A Research Application for Image-Guided Therapy
No opinion
CustusX version 3 is an in-house application for research in image-guided therapy with a focus on intraoperative use and ultrasound imaging. It is built upon open source toolkits such as the Insight Toolkit (ITK), the Visualization Toolkit (VTK), Qt and [...]

A File Reader for the VisualSonics Vevo 770 Digital RF Data
A C++ file reader for the VisualSonics Vevo® 770 high frequency ultrasound system is presented. The digital RF header file is read into an XML DOM representation, which can be serialized as XML, HTML, or accessed in C++ natively with data object binding. [...]

An Open Source, Fast Ultrasound B-Mode Implementation for Commodity Hardware
This document describes an open source, high performance ultrasound B-Mode implementation based on the Insight Toolkit (ITK). ITK extensions are presented to calculate the radio-frequency (RF) signal envelope. A variety of 1D Fast Fourier Transform options [...]

Automatized Evaluation of the Left Ventricular Ejection Fraction from Echocardiographic Images Using Graph Cut
No opinion
In this paper, we present a fast and interactive graph cut method for 3D segmentation of the endocardial wall of the left ventricle (LV) given 3D echocardiographic images. This is a challenging task due to the poor contrast and the low signal-to-noise ratio [...]

Challenge on Endocardial Three-dimensional Ultrasound Segmentation (CETUS)
No opinion
Real-time 3D echocardiography has already been shown to be an accurate tool for left ventricular (LV) volume assessment. However, LV border identification remains a challenging task, mainly because of the low contrast of the images combined with drop-out [...]

Clinical Expert Delineation of 3D Left Ventricular Echocardiograms for the CETUS Segmentation Challenge
No opinion
Within the framework of the CETUS challenge, forty-five 3D echocardiographic datasets have been acquired and segmented independently by three clinical experts from different hospitals. The goal was to generate a well-established ground truth of validated [...]

Probabilistic Tissue Characterization for Ultrasound Images
No opinion
This document describes the derivation of the mixture models commonly used in the literature to describe the probabilistic nature of speckle: The Gaussian Mixture Model, the Rayleigh Mixture Model, the Gamma Mixture Model and the Generalized Gamma Mixture [...]

The MUSiiC Toolkit: Modular Real-Time Toolkit for Advanced Ultrasound Research
No opinion
Ultrasound is a very useful and convenient modality in medical imaging, due to its relatively small footprint, high resolution, negligible adverse effects, and real-time imaging capability -- in spite of its well-known artifacts. However, it is fairly [...]

OpenITGLinkMUSiiC: A Standard Communications Protocol for Advanced Ultrasound Research
No opinion
Ultrasound imaging is the most popular and safe diagnostic medical imaging modality. Over the past years, a considerable number of studies have been conducted on new medical ultrasound imaging modalities such as ultrasound-based elasticity imaging, [...]

MUSiiC ToolKit 2.0: Bidirectional Real-time Software Framework for Advanced Interventional Ultrasound Research
No opinion
Ultrasound (US) imaging is a popular and convenient medical imaging modality thanks to its mobility, non-ionizing radiation, ease-of-use, and real-time acquisition. Conventional US imaging is frequently integrated with tracking systems and robotic systems in [...]

Fast Tracking of the Left Ventricle Using Global Anatomical Affine Optical Flow and Local Recursive Block Matching
No opinion
We present a novel method for segmentation and tracking of the left ventricle (LV) in 4D ultrasound sequences using a combination of automatic segmentation at the end-diastolic frame and tracking using both a global optical flow-based tracker and local block [...]

An Open-Source Solution for Interactive Acquisition, Processing and Transfer of Interventional Ultrasound Images
