Assistant Professor & PULSE Lab Director - Johns Hopkins University Department of Electrical and Computer Engineering Department of Biomedical Engineering Listening to the Sound of Light to Guide Surgeries Abstract Photoacoustic imaging offers “x-ray vision” to see beyond tool tips and underneath tissue during surgical procedures, yet no ionizing x-rays are required. Instead, optical fibers […]

From Ocular Biometry to Cellular Resolution – and Multifunctional OCT – Coherence Ranging and Imaging in the Human Eye over 35 Years Abstract In the mid 1980s, first applications of low coherence interferometry (LCI) to tissue metrology and analysis were reported. Starting from one-dimensional ocular biometry, the technology has evolved into a high-speed, 3-dimensional imaging […]
