Re-imagining Ultrasound and Photoacoustic Imaging: Biomedical Engineering (BME 500) Seminar Series - Roger Zemp, Ph.D.

Paradigm shifts in technology are needed for next-generation ultrasound imaging. We introduce novel electrostrictive row-column array technology that promises improved 3D image quality and ultrafast imaging speeds. Moreover, these advances will lead to arrays of unprecedented size and novel form-factors such as endoscopic probes and wearable band-aids that will mitigate operator dependence and lead to longitudinal imaging opportunities. Our technology enables readout from every element of the 2D array using only row and column addressing, and is well-suited to volumetric photoacoustic imaging using pulsed laser excitation to image optical properties of tissues. Novel agents and genetically-encoded reporters will be introduced. Applications to brain imaging, cardiovascular medicine, small animal imaging will be discussed. Furthermore, a new non-contact all optical form of photoacoustic imaging will be discussed with applications to virtual histology of tissues.

Roger Zemp earned his PhD from UC Davis in 2004 and after three years of postdoctoral work in the Laboratory of Prof. Lihong Wang, joined the Faculty in the Department of Electrical and Computer Engineering and Biomedical Engineering at the University of Alberta in 2007. He is a recognized international leader in the field of photoacoustic imaging and ultrasound imaging. He has co-founded two startup companies and maintains an active laboratory at the intersection of ultrasound, optics, micro-nano-fabrication, and in vivo imaging. ​​​​​​​
