Biological Systems Engineering

Biomedical Imaging and Biosignal Analysis Laboratory

This laboratory, constructed in 2004, provides support for biomedical engineering research. The laboratory includes a scan area and conventional bench-top space. Major lab equipment includes a Siemens Antares commercial diagnostic ultrasound machine, tissue-mimicking phantoms, a ventilation hood, ultrasonic pulsers/receivers, arbitrary function generators, RF power amplifiers, digital oscilloscopes, and several custom-built translation tables. In addition, several National Instruments DAQ cards are contained within high-power workstations. Computing resources include MATLAB®, LabVIEW, and Visual C++ software. Most experimental setups are capable of full computer control. The laboratory is used for medical imaging studies and biosignal analysis, such as ultrasound mammography for breast cancer screening, echodentography, cardiovascular flow quantification, ECG/EEG instrumentation, and evoked potentials for neurological experiments.
