2020-441 OPTICAL IMAGING METHOD FOR INTRAOPERATIVE SURGICAL GUIDANCE AND MARGIN ASSESSMENT BASED ON FLUORESCENCE LIFETIME CONTRAST

UCLA researchers from the Department of Head and Neck Surgery have developed a novel optical imaging method for surgical guidance. BACKGROUND:Biomedical imaging is an indispensable tool to guide in precise tumor removal in comprehensive cancer surgery. Imaging strategies like x-ray, ultrasound, and MRI are principally used to localize large tumors prior...

2020-493 SELECTIVE SPECTRAL ILLUMINATION METHOD AND SYSTEM FOR OPTICAL IMAGE GUIDED SURGERY

UCLA researchers in the Department of Head and Neck Surgery have developed a novel selective spectral illumination system for optical image-guided surgery. BACKGROUND:In oncological surgery, patient prognosis depends heavily on complete tumor removal. Currently, surgeons have to rely on subjective evaluations (e.g. visual appearance) to distinguish...

2010-142 TIME-RESOLVED FLUORESCENCE IMAGING WITHOUT LIFETIME FITTING

Time-Resolved Fluorescence Imaging Without Lifetime FittingSUMMARYUCLA investigators have developed a novel method to obtain time-resolved fluorescence imaging (TRFI) without the need to extract a fluorescence lifetime. Compared to conventional TRFI, this novel method is reliable, simple, time-saving and can dramatically improve biomedical applications...
