    Collapse Overview
    Dr. Zhou’s research focuses on the design and fabrication of high frequency ultrasonic transducers using new piezoelectric single crystal and thin film technologies for medical imaging applications. He has integrated ultrasonic technology with advanced optical technology for intravascular imaging application. His current work is to develop miniaturized photoacoustic imaging (PA) probes using high frequency ultrasound transducers for endoscopic application. The primary motivations are to overcome the depth limitation of existing endoscopic imaging technologies and to provide functional information for disease states via photoacoustic imaging.
