About the Medical Ultrasound Physics and Technology Group

(Telephone: +353-1-4024783)

The Medical Ultrasound Physics and Technology group was established in 2005 and is based in FOCAS Institute in the Dublin Institute of Technology and in the School of Physics, room KE 116 in Kevin Street. The group concentrates on the medical ultrasound physics and technology, disease characterisation using ultrasonic techniques and performance testing of medical ultrasound equipment.

The current research programs include: disease characterisation in the renal system and the development of contrast resolution phantoms and anthropomorphic breast phantoms as well as the development of new performance test devices for cardiac ultrasound quality control measurements. Specifically, these projects focus on the development of in-vitro anatomical experimental systems, which closely mimic human anatomical systems, in order to gain a better understanding of the disease process, as well as to serve the needs of clinical practitioners and manufacturers of medical imaging equipment and accessories.

Projects

Use of Medical Ultrasonic Imaging Techniques to Determine the Biomechanical Status of Disease Progression in the Renal Artery

This project involves the development of anatomically realistic renal artery flow phantoms and perfusion phantoms. An evaluation of current non-invasive ultrasound techniques, capable of diagnosing stenosis in the renal artery is currently being undertaken. All of the previous objectives are being undertaken in order for an understanding of disease progression in the renal artery through experimentation to be gained, thereby improving the outcome of various treatment regimes by the early detection of the disease. This work is carried out in collaboration with Dr. Carmel Moran from the Medical Physics Unit at the University of Edinburgh.

Development of a Clinically Relevant Quality Assurance Phantom and an Anthropomorphic Phantom for Breast Ultrasound Imaging

This project involves the development of High frequency contrast resolution phantoms and anthropomorphic breast phantoms for breast ultrasound imaging. The hypothesis of this study is that clinically relevant Quality Assurance phantoms may refine the currently used Quality Control procedures and also anthropomorphic training phantoms may improve the ability of operators to detect and diagnose lesions during breast ultrasound examinations, thereby improving patient outcomes through better quality ultrasound scans. This work is carried out in collaboration with Dr. Andrew Fagan from the Centre of Advanced Medical Imaging in St James's Hospital and BreastCheck Ireland.

Development of Performance Test Procedures and Devices for Cardiac Ultrasound Systems

Due to the rapid rate at which the performance and imaging capabilities of ultrasound scanners are being improved, designing performance test procedures and test phantoms which will challenge state-of-the art, top-of-the range ultrasound scanners represents a growing challenge. A further problem is that the results obtained from these performance test procedures have rarely been found to be reflective of the ultrasound scanner’s clinical performance. It is imperative that these performance and quality control (QC) test protocols and test devices keep pace with developments in medical ultrasound technology – one only has to look at the plethora of new imaging modes appearing on modern-day ultrasound scanners to gain an appreciation of how far the test protocols and devices are falling behind what should be considered a minimum standard. In general, separate test protocols have been produced for both B-mode and Doppler testing, and this approach is adopted for the areas of ultrasound QA research of this research programme. The first area of ultrasound QA research addresses the problems associated with the testing of B-mode image quality performance across a range of ultrasound scanners. An ideal test procedure and test phantom would be able to differentiate ultrasound scanners of varying complexity and clinical perception of image quality. This area of ultrasound QA research addresses the problems associated with testing colour and power Doppler image quality performance. This work is being carried out in collaboration with Dr. Andrew Fagan from the Centre of Advanced Medical Imaging in St James's Hospital.

Collaborations

The Medical Ultrasound Physics and Technology Group is working closely with a number of medical physicists and clinical practitioners to develop specific anatomical experimental models of the renal artery and the breast in order to gain a better understanding of disease progression in these biological systems. The group also works with various medical device companies in order to investigate possible refinements to current technology and also to improve the operation of medical devices by gaining an understanding of the physics and technology of these devices.

Current Collaborators are listed below:

Public Engagement Work

Dr Browne successfully obtained from the Institute of Physics in 2007 to establish a public engagement workshop in the area of Physics in Medicine to inform secondary school students of the exciting careers possible with physics in the area of medicine. The members of the Medical Ultrasound and Physics group all take part in this work of the IOP public engagement Medical Physics group “Physics makes you better”, in the School of Physics in the Dublin Institute of Technology.
