The field of Biomedical Imaging and Sensing integrates multiple disciplines of electrical and computer engineering to solve problems of critical importance in clinical medicine. Topics of research activity include acoustic and stereo imaging, magnetic resonance imaging, finite element analysis of cardiac responses, induced currents and nerve stimulation from electromagnetic fields, and electronic medical databases. The results of this research are expected to improve diagnostic accuracy, improve the safety of diagnostic instrumentation, and enhance patient recovery through improved clinical instruments.
One of the goals of biomedical research is to develop inexpensive acoustical instruments to monitor pathological changes in non-critical environments such as the home or the physician's office. Acoustics are also being used to guide the placement of breathing tubes in infants. Signal processing and filtering algorithms are being applied to the development of a new generation of stethoscopes that function in high-noise environments such as helicopters and ambulances.
World renowned expertise in imaging is being applied to stereo visualization for mammography diagnostics and acoustic imaging of the lung. An experimental study of the intensities of MRI fields required to produce nerve stimulation in humans is expected to result in lower cost imaging, improved accuracy, and enhanced patient safety.
The facilities of the Biomedical Acoustics Laboratory are used for research in electroacoustic principles as well as research and development of non-invasive clinical instruments. The laboratory consists of a soundproof chamber that provides both acoustical and electromagnetic shielding and extensive measurement and processing equipment.
