Research Exhibit, MR Imaging Group

The University of Texas at Arlington

Welcome to the Magnetic Resonance Imaging Group, which is a research entity within the organizational framework of the Electrical Engineering Department, The University of Texas at Arlington. This exhibit has been prepared to demonstrate our latest advances related to acquisition, processing, and visualization of medical images generated using Magnetic Resonance Imaging technology. The work presented here is a result of the collaboration with the Department of Radiology, Southwestern Medical Center at Dallas , which is another unit of the University of Texas system, and serves as our clinical facility. Additional support for some of the presented work has been provided by Picker International.

As you will notice, our research is focused primarily on the engineering aspects of Magnetic Resonance Imaging. It includes the design and development of imaging instrumentation and improvements to image acqusition and signal processing techniques. In addition, we are actively pursuing the development of automated imaging processing techniques which implement functional MR imaging by allowing automated extraction and quantification of anatomical and physiological data from function-specific MR images.

For your convenience, we are posting copies of some of our more recent converence presentations, and accompanying slides. We reserve, however, full rights to these materials and request that you do not copy an portion without the explicit approval of the authors.

Thank you, and we hope to hear from you in the future!

Ongoing research topics

Echo-Planar Image Acquisition

This area of research focuses on the design improvements to the commercial MR scanners which facilitate the implementation of the Echo Planar Imaging (EPI) method with total acquisition time in the range of a 100ms, thus enabling the new work on functional imaging of cardiovascular and central nervous system.

Cardiac Functional Imaging

Using a combination of magnetic tagging techniques and flow-sensetive MR imaging, a fully automated system for the comprehensive assessment of cardiac function is being developed. Special attention is given to segmental wall motion analysis, and quantitative analysis of the arterial and ventricular blood flow and volumetries.

MR Gradient Coil Design

Research invloving design and development of high-performance gradient array coils for use in Echo-Planar MR imaging and microscopic MR imaging.

Intravenous Catheter Coil Design

This is a relatively new effort focusing on the design and applications of miniature MR receivers which can be integrated with standard cardiac catheters for obtaining high-quality MR images of the vascular anatomy with specific applicability in monitoring of atherosclerotic disease.
