The present disclosure relates to non-invasive nerve identification using snapshot polarimetry. The present disclosure further relates to a system for nerve identification, the system comprising a camera including a sensor, and a filter having a linear polarizer array, an illumination system configured to illuminate a target area with polarized light illumination, the polarized light illumination having at least one predetermined polarization angle, the illumination system including one more light sources, and one or more polarizer filters, and a processor configured to process imaging data obtained from the camera, and output a birefringence map of the target area including indicia of a nerve structure.

System and method for intraoperative, non-invasive nerve identification using snapshot polarimetry

Heptamethine cyanines for use as fluorescent markers of the biliary and renal systems are disclosed. Certain heptamethine cyanines exhibit renal system specificity, while others exhibit biliary system specificity. The compounds may be used for diagnostic purposes and/or for visualization of renal or biliary systems during surgery.

The present disclosure is related to a method and apparatus for providing recommendation for a medical surgical procedure, including acquiring, using circuitry, a plurality of multispectral images representing a portion of an anatomy of a patient, performing image processing on each of the plurality of multispectral images to form a plurality of value maps, each value map identifying aspects of the portion of the anatomy by assigned values, combining the plurality of value maps into a single recommendation map, determining optimal points for performing the medical surgical procedure based on the single recommendation map, and displaying the optimal points for the medical surgical procedure by overlaying the optimal points on an original image of the portion of the anatomy or applying the optimal points to a robotic medical surgical procedure.
