Recently the Royal Academy of Engineering Sciences, Kungliga ingenjörsvetenskapsakademin, awarded a grant of 100 000 SEK to a research project on bioimpedance and analysis of measurement of electrical signals in the brain after stroke. Now the former student at the University of Borås, Seyedreza Atefi who studied biomedical engineering, can go to Harvard University for nine months to conduct studies and experiments with measurement and analysis of bioimpedance in the brains of patients associated with stroke.
Communication and signal processing was an area that Seyedreza Atefi found very interesting while studying at the University of Borås, and led him to continue the research in biomedical engineering.
Hope for boost for research on bioimpedance
"Today stroke patients mainly are scanned with MRI and CT that provides a visual image of the brain. But this form of investigation is both time and cost consuming. We try to develop a tool that can be used before you can get to MRI and CT", explains Seyedreza Atefi.
The study with electrodes provide no visual image, but the reseachers on bioimpedance mean that you can get an idea of the situation in the brain using this method.
"The method of measuring bioimpedance is not currently developed for scanning of the brain. We hope that we can now lift the research to new levels. Through the collaboration with Harvard, we will have access to more measurement data and a larger group of patients".
The research in biomedical engineering at the University of Borås focuses on the so-called bioimpedance. This means that you supply current via electrodes and measures the signals passing through the various layers of fat and fluid in the body. The signals can reveal e.g. if there is a bleeding or if cellular tissue is dead.
At Harvard, they are also interested in bioimpedance and they have shown interest in collaboration with the research group in biomedical engineering. Other stakeholders in the project are Karolinska Institute, Massachusetts General Hospital.
On July 1 Seyedreza Atefi will start the studies and experiments at Harvard in the U.S.
was awarded the 1-year master's degree in electrical engineering - biomedical engineering in 2010 and could, through a collaboration between Chalmers and the University of Borås complete a 2 year Master’s programme. Then he got doctoral student posiotion at KTH, where he is currently conducting its second research year. Dr. Fernando Seoande, engaged as a researcher at the University of Borås as well as at the KTH, is the co-supservisor for Seyedreza Atefi on this research project.
