Abstract

This study aims to integrate real-time hyperspectral (HS) imaging with a surgical microscope to assist neurosurgeons in differentiating between healthy and pathological tissue during procedures. Using the LEICA M525 microscope’s optical ports, we register HS data and RGB, in an efforts to improve margin delineation and surgical outcomes. The CUBERT ULTRIS SR5 camera with 51 bands and 15 Hz is employed, and critical calibration steps are outlined for clinical application. Experimental validation is conducted on ex-vivo animal tissue using reflectance spectroscopy. We present the preliminary validation results of the performance comparison between the designed hyperspectral imaging microscope prototype and diffuse reflectance spectroscopy conducted on animal tissue.
