Dr. Lihong Wang(Professor, Medical and Electrical Engineering, Caltech), one of the inventors of Photoacoustic Imaging was hosted SPIE/OSA student chapter. He gave a talk on Photoacoustic Tomography titled "“Photoacoustic Tomography: Ultrasonically Beating Optical Diffusion". It was a great talk with a huge turnout. Many students, staff and faculty member showed up for the talk.


Summary of the talk:

Photoacoustic tomography (PAT), combining optical and ultrasonic waves via the photoacoustic effect, provides in vivo functional, metabolic, molecular, and histologic imaging. PAT has the unique strength of high-resolution imaging across the length scales of organelles, cells, tissues, organs, and small-animal organisms with consistent contrast. PAT has the potential to empower holistic omniscale biology research and accelerate translation from microscopic laboratory discoveries to macroscopic clinical practice. Potential applications include imaging of the breast, brain, skin, esophagus, colon, vascular system, and lymphatic system in both animals and humans.
