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 to improve the reliability and reproducibility of 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.
