Broadly, our group is interested in quantifying tissue microstructure using ultrasound imaging. This is accomplished by investigating elastography and acoustic scattering. Learn more at our research page!
The Quantitative Ultrasound Lab is actively looking for new members. Interested parties are encouraged to contact Dr. Timothy Hall.
Research
Tissue stiffness has great clinical relevance, dating back centuries to palpation exams. Ultrasound imaging is capable of objectively characterizing how tissues deform under compression or how shear waves travel resulting from acoustic radiation forces. Both approaches yield metrics related to fundamental mechanical quantities.
A common assumption of quantitative measures derived from backscattered ultrasound data is that tissue is composed of small, randomly distributed objects that interact with the ultrasound pulse, defining a resolution cell. In reality, tissue is more complex than this (see the classification decision tree). Our group has developed algorithms to test these assumptions and provide measures that classify different scattering scenarios.
