In one embodiment, the system includes a light source configured to emit a source light; at least one optical probe; a scanner; a spectrometer; and a controller coupled with the scanner and the spectrometer for operably controlling the scanner and the spectrometer. In operation, a working end of the optical probe is positioned proximate to a surface of a specimen of the tumor tissues. A source channel of the optical probe deliver the source light emitted by the light source from the working end to the surface of the specimen, and a plurality of collection channels collect from the working end diffused/reflected light generated from interaction of the source light with the specimen. The spectrometer receives the collected diffused/reflected light to evaluate a margin status of the specimen."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and systems for three-dimensional real-time intraoperative surgical margin evaluation of tumor tissues","description":"In one aspect, the present invention relates to a system evaluating a surgical margin of tumor tissues of a living subject.
