CANCELED: Advances in Tissue Differentiation: Combining Optical Coherence Tomography and Diffuse Reflectance Spectroscopy

10 April 2024 • 11:50 - 11:50 CEST | Etoile B, Niveau/Level 1

Abstract

Feedback systems are crucial for a safe and accurate laser surgery. Optical coherence tomography (OCT) offers valuable feedback, including visual feedback and tissue differentiation. Detecting tissue type is important to avoid harming adjacent critical tissue, though water and blood in surgical settings may affect OCT’s precision. To address this, we integrated OCT and diffuse reflectance spectroscopy (DRS) for enhanced accuracy.This study employs a 1300 nm swept-source OCT with a 2x2 fiber coupler and double-clad fiber. DRS illumination is integrated, and data is collected using a double-clad fiber, analyzed by a spectrometer. The system’s performance is evaluated on various tissue types.
