Hyperspectral Imaging (HSI) is a contact free method to analyse the from the tissue reflected light in the range of 500-1000nm. Aim of the study is to identify special reflex patterns to identify special tissue
This HSI-camera provides hyperspectral images with a high spectral resolution (5 nm) in the visible and near infrared range (500-1000 nm). A RGB image and 4 false color images that represent physiologic parameters are intraoperatively provided by an analysis software. But after the procedure all spectral datasets could be investigated. To analyse and differentiate the different tissues, a catalog database is needed of all tissues including Tumors.
