Abstract:

Detecting, measuring and quantifying blood perfusion in the human tissues is a significant problem not well characterized by todays instruments. Tissue perfusion, or blood flow in the microcirculation, is an important indicator of the relative health of tissue, relating directly to tissue oxygenation and nutrition, as well as toxic metabolite removal. In this Phase I project we endeavored to answer this need with a new technology involving the ultrasound detection and quantification of this parameter, utilizing a harmless, injectable contrast agent. We designed and tested a system for this method, and serendipitously discovered and developed an alternate method that may prove to be more robust than the original one proposed.
