2:45pm-3:45pm Intravascular Imaging with Optical Coherence Tomography (OCT), with Dr. Joseph M. Schmitt, Chief Technical Officer, LightLab Imaging
Abstract: The introduction of optical coherence tomography (OCT) into the marketplace for ophthalmic imaging marks the successful transfer of a new imaging technology from the research bench to the patient's bedside. This talk will trace the development of an important new emerging application of OCT: imaging inside the coronary arteries. The talk will highlight technical advances in swept-source laser design made by LightLab Imaging, a start-up company founded to commercialize technology developed originally at the Massachusetts Institute of Technology. Results from clinical studies will be presented in which OCT is used for guidance of stent implantation and other coronary interventions.
4:00pm-5:00pm New Techniques in Biological Imaging, with Prof. Jerome Mertz, Boston University, Biomedical Engineering Department
Light microscopy has undergone a renaissance in recent years. In 1990, Webb and Denk demonstrated the possibility of generating two-photon excited fluorescence (TPEF) to produce biological images with sub-micron resolution in thick tissue. Since then, TPEF microscopy has gained widespread interest, particularly in neurobiology and developmental biology. Nonlinear contrast mechanisms may also be based on scattering instead of absorption. For example, second-harmonic generation (SHG) microscopy, which actually predates TPEF microscopy, is gaining renewed attention as a unique tool for the visualization of cell membrane potential.
