Department of Biomedical Engineering and Dermatology, Oregon Health & Science University Biomedical Optics: Imaging and characterizing tissues Abstract Tissue optics describes the interactions of biological tissues and light that influence the propagation of light in the tissue. Tissue optics is pertinent to both therapeutic dosimetry and diagnostic imaging, characterization, and sensing. Historically, early work in biomedical optics dealt with laser effects and propagation and deposition of optical energy was the key issue. Hence, descriptions of light transport concentrated on delivery of intensity and energy. Later work with optical coherence tomography and other interferometric techniques emphasized the propagation of light as an electromagnetic wave, and the phase and coherence of wavefronts became more significant. This talk will discuss progress in characterizing tissues by optical techniques. Current work is presented on imaging using polarized light imaging, reflectance-mode confocal microscopy and optical coherence tomography, and on spectroscopic characterization using an optical fiber spectrometers.Biosketch Steven L. Jacques, Ph.D., has been working in the field of biomedical optics and laser-tissue interactions for 21 years. He studied biology at MIT (B.S. 1975), and electrical engineering (M.S.E.E. 1979) and biophysics/medical physics (Ph.D. 1984) at the University of California at Berkeley. He worked 5 years at the Wellman Laboratories for Photomedicine at Massachusetts General Hospital in Boston (Lecturer, Dermatology/Biomedical Engineering, Harvard Medical School) and 8 years at the University of Texas M. D. Anderson Cancer Center in Houston (tenured Assoc. Professor, Urology/Biophysics). He has now worked 8 years in Portland, Oregon, and is a Professor of Biomedical Engineering and Dermatology at the Oregon Health & Science University. His research has been funded by federal grants from the NIH, NSF, ONR, DOE, and AFOSR, and by various foundations.Wednesday, December 1, 2004
