This new scanner is 100 to 1,000 times faster than previous PAT units permitting tissue imaging in a few seconds rather than the previous 5 minutes or more.  This yields significantly sharper images by eliminating patient movement effects. The unit is invaluable for imaging blood vessels in fingers, oral structures like the tongue, and vasculature in the extremities of diabetics.  This remarkable photo acoustic tomography should be in clinical use… someday soon https://www.nature.com/articles/s41551-024-01247-x #photoacoustictomography #pat #bloodsvessels #ultrasound #imaging
