MTW lunch seminar with professor Paul Meaney on Microwave Tomography: Translation to the Clinic

Paul MeaneyThere has been a wide range of interest and hype surrounding microwave imaging for a number of decades. Much of the interest has centered in academia and especially in the numerical modeling realm. The major motivations are that tissue dielectric properties can be remarkably specific and that microwave radiation is nonionizing. For instance, breast tumors generally have higher dielectric properties than normal breast tissue - a possible mechanism for cancer detection.

In addition, recent studies show that bone dielectric properties change with bone density – a possible alternate to x-ray densitometry for monitoring bone loss. Blood properties are different than those for brain tissue – possible applications in stroke diagnosis. These are only a few potential medical applications.

Professor Paul Meaney´s group is one of the only groups in the world to have an actual working tomography system in the clinic. A large part of this success is related to the unconventional and counterintuitive antenna array they use. This development has been a unique synergism of hardware and software expertise which has allowed them to perform hundreds of patient breast exams along with a small pilot study looking at bone screening.

At this seminar, Meaney will briefly discuss some of the more daunting implementation challenges and how they’ve addressed them. This will include their unique algorithmic approach, which now allows them to reconstruct images from exams in only a few minutes compared to hours to days for other modeling groups. In addition, this approach has allowed them to apply a fairly simple hardware configuration that keeps the number of antennas and transmit/receive pairs to a minimum and dramatically impacts the overall system cost. Complementing this design, they’ve also directly addressed multi-path signal interference problems which plague most system implementations. Professor Meaney will show some images from his clinical system including a variety of breast cancer detection and therapy monitoring examples.

Dr. Paul Meaney´s research has focused mainly on microwave tomography which exploits the many facets of dielectric properties in tissue and other media. His principle interest over the last decade has been in the area of breast cancer imaging where his group was the first to translate an actual system into the clinic. His team has published several clinical studies in various settings including: (a) breast cancer diagnosis, (b) breast cancer chemotherapy monitoring, (c) bone density imaging, and (d) temperature monitoring during thermal therapy. Dr. Meaney holds 10 patents, has co-authored 70 peer-reviewed journal articles, co-written one textbook and presented numerous invited papers related to microwave imaging.

BIOGRAPHY: Dr. Paul Meaney received AB’s in Electrical Engineering and Computer Science from Brown University in 1982. He earned his Masters Degree in Microwave Engineering from the University of Massachusetts in 1985 and worked in the millimeter-wave industry at companies including Millitech, Aerojet Electrosystems and Alpha Industries. He received his PhD from Dartmouth College in 1995 and spent two years as a postdoctoral fellow including one year at the Royal Marsden Hospital in Sutton, England. His research has focused mainly on microwave tomography which exploits the many facets of dielectric properties in tissue and other media. His principle interest over the last decade has been in the area of breast cancer imaging where his group was the first to translate an actual system into the clinic. His team has published several clinical studies in various settings including: (a) breast cancer diagnosis, (b) breast cancer chemotherapy monitoring, (c) bone density imaging, and (d) temperature monitoring during thermal therapy. He has also explored various commercial spin-off concepts such as detecting explosive liquids and non-invasively testing whether a bottle of wine has gone bad. He has been a Professor at Dartmouth since 1997, a professor at Chalmers University of Technology, Gothenburg, Sweden since 2015, and is also President of Microwave Imaging System Technologies, Inc. which he co-founded with Dr. Keith Paulsen in 1995. Dr. Meaney holds 10 patents, has co-authored 70 peer-reviewed journal articles, co-written one textbook and presented numerous invited papers related to microwave imaging.
