During BioEM2017, a joint annual meeting between the Bioelectromagnetics Society (BEMS) and the European BioElectromagnetics Association (EBEA), our 2nd annual Arthur Pilla Young Scientist Award winner was selected! The meeting, which took place June 5-9, 2017 in Hangzhou, China, had 5 entries this year- with topics ranging from nerve stimulation by PEMF, modeling of electroporation, magnetophosphene perception at Extremely Low Frequency magnetic fields and bacterial absorption of THz.
Dr. Manuel Murbach, from Zurich, Switzerland, was chosen as our winner for having the best presentation this year with his study entitled, “Numerical MRI Radiofrequency Exposure Estimation in Morphed Patient Anatomies”. Manuel won a $1,200 cash prize, as well as a copy of Dr. Marko Markov’s book, “Dosimetry in Electromagnetics”, donated by Dr. Markov.
Read on to learn about the study “Numerical MRI Radiofrequency Exposure Estimation in morphed patient anatomies” and about Manuel’s view of the importance of a Young Scientist Award.
Background: In 2008, Manuel conducted a study on the effect of mobile phones on human sleep. His current MRI safety study involve electromagnetic fields that are 100 times stronger than mobile phones. For humans, as Magnetic Resonance Devices evolve and get stronger and faster, our safety protocols for new machines must be updated and modified. FDA approval for all new machines is complex and this study seeks to aid and simplify this process for manufacturers. When studying the effect of an MRI on human tissue, certain virtual body models are used, but Manuel found that there are currently not enough body types offered, therefore he developed a system whereby one can choose any body type to put into a virtual MRI machine and simulate how the radiation travels and can effect human fat and muscle tissue. Manuel developed this MORPH tool to make it easier to see the effect of an MRI on someone with more muscle tissue, for example. “We can cover more patient anatomies with this tool and get a better view on how an MRI affects certain human body types”, states Manuel. For example, we can answer the question of whether obesity lowers or increases the safety of an MRI for certain body types. At first glance, it looked like having more body fat was actually a good thing, and those with leaner bodies and more muscle tissue were more affected. The new generations of MRI devices have quite different excitation technologies in order to among other things, speed up image taking, and these new machines need to be tested for safety. MRI manufacturers must prove to the FDA that they have covered all types of scenarios and this tool will make it easier for manufacturers to do just that, which in turn translates to better patient safety. A win-win in my book!
“In the end, we are moving in the right direction and this study could potentially lead to a new protocol on how to measure MRI safety on ALL body types, whether we have more or less muscle tissue, whether we have a very slight frame and not much fat around our organs, or if there is a lot of fat tissue”, says Manuel. All of these factors can impact the effect an MRI can have on tissue and organs.
For Manuel, having a young student award stimulates creativity and energizes meetings. It motivates young scientists to do their best and gives a certain environment of positive challenge and competition to the meetings, something that is very important in getting our younger scientists interested and involved. I love to hear this and cannot wait to award our Third Annual Arthur Pilla Young Scientist Award in Slovenia next year! So get your submissions in soon and see you in Slovenia!
For those very young scientists out there, it’s always interesting to find out how a scientist arrived at their present day activity. In Manuel’s case, he started in electro-technical engineering studies, which he did not fully enjoy. He ended up earning a Master’s Degree in Biomedical technology. “The interaction between tech and humans is what I like”, says Manuel. That, coupled with a love of teaching and social service is why Manuel does what he does today. Manuel is currently working at The Foundation for Research on Information Technologies in Society (IT’IS) – a non profit organization dedicated to improving our quality of life by enhancing the safety and quality of emerging electromagnetic technologies.
