PURPOSE/BACKGROUND Previous research studies by Bolga, Ayotte, and Distefano have examined the level of muscle recruitment of the gluteal muscles for various clinical exercises; however, there has been no cross comparison among the top exercises from each study. The purpose of this study is to compare top exercises from these studies as well as several… (More)
The downhill filter is an elegant and efficient single pass reconstruction algorithm which demonstrates fast and consistent performance. It operates through a controlled process of region growing by ordered aggregation of surface pixels onto an expanding shell.
OBJECTIVE The purpose of this article is to determine the feasibility of using computer-assisted diagnosis (CAD) techniques to automatically identify, localize, and measure body fat tissue from a rapid whole-body MRI examination. CONCLUSION Whole-body MRI in conjunction with CAD allows a fast, automatic, and accurate approach to body fat measurement and… (More)
Frequently MRI data is characterised by a relatively low signal to noise ratio (SNR) or contrast to noise ratio (CNR). When developing automated Computer Assisted Diagnostic (CAD) techniques the errors introduced by the image noise are not acceptable. Thus, to limit these errors, a solution is to filter the data in order to increase the SNR. More… (More)
In recent years non-invasive medical diagnostic techniques have been used widely in medical investigations. Among the various imaging modalities available, Magnetic Resonance Imaging is very attractive as it produces multi-slice images where the contrast between various types of body tissues such as muscle, ligaments and fat is well defined. The aim of this… (More)
The successful realization of the goal of Model-Based Systems Engineering (MBSE) practice, to contain all project information in models, is predicated on the ability of the system model to represent the information needs of a broad range of stakeholders such as the owners, acquirers, suppliers, maintainers, and users. The paper opens by discussing the… (More)
Magnetic Resonance Cholangiopancreatography (MRCP) is a type of MR imaging which utilises protocols designed to enhance stationary fluids in the imaged volume. In this way it visualises the pancreatobiliary tract by highlighting the bile and pancreatic juices in the system. Current practice sees this data being assessed directly, with little or no… (More)
As whole body MRI (WB-MRI) gains currency, the data this class of technique generates presents new challenges for the imaging community. One acquisition protocol currently being applied with considerable success entails imaging the subject in a number of successive coronal sections, resulting in a high resolution, gap free, full body acquisition. However… (More)
