Abstract
In the twenty-first century the impact that physics is making on the practice of diagnostic and therapeutic medicine is nothing short of staggering. Since 2009 I have been interested in the use of laser light to reconstruct functional images in human tissue and in the determination of blood flow parameters. The research is in collaboration with the Biomedical Imaging group at the University of Pennsylvania. In this talk I will describe the field of diffusive optical tomography, and explain ongoing work with our third generation instrument - currently undergoing clinical testing - to obtain tomographic images of breast cancer. I will also describe a new project for a pre-clinical study of the fundamentals of ischemic stroke using a method known as laser speckle imaging. Using laser light as a diagnostic tool is simpler and less expensive than other methods and free from the effects of ionizing radiation.
