The HiLight Solution
HiLight Surgical has developed a fiber optic-based imaging system designed with the purpose of intraoperative verification of tissue margins or biopsy results immediately in real-time. This simple, low-cost system utilizes label-free Fluorescence Lifetime Imaging (FLIm) technology enhanced with AI-ML.
Technology: Fluorescence Lifetime
Fluorescence is the phenomenon during which a substance absorbs light at one wavelength and then re-emits it at a different, and usually longer wavelength. The color or spectrum of emitted fluorescence light is characteristic of molecules present in the tissue.
The speed of fluorescence emission and characteristic decay curve, called fluorescence lifetime, also varies depending on the molecules present in the tissue.
Section Title
Using AI-ML we analyze both spectral (color) and lifetime information to provide tissue identification.
Leveraging these tissue fingerprint differences allows HiLight to discriminate between healthy and malignant tissue
