Biography
James Lacefield, Ph.D., Biomedical Engineering, Duke University, Professor, Electrical & Computer Engineering and Medical Biophysics of department of Computer Engineering at the University of Western Ontario, Canada. James Lacefield is a biomedical engineer with expertise in the physical acoustics and signal processing aspects of ultrasound imaging. Dr. Lacefield’s research program focuses on development of new methods and systems for quantitative microvascular imaging and image-guided injections, with an emphasis on applications of high-resolution ultrasound to cancer research. Our current research projects include development of signal processing and image optimization methods for colour Doppler, power Doppler, and contrast-enhanced ultrasound imaging, development of novel methods to quantify changes in the spatial distribution of blood flow in tumours, and design of an automated system for targeted injections of cell-based cancer vaccines.
Research Interest
