摘要
A surgical drilling system for determining proximity of a surgical drill bit to an artery during a drilling procedure, including an excitation and/or collection optical channel of a spectral absorption probe, wherein the excitation channel provides light configured for absorption by blood chromophores and the collection channel captures diffused back-scattered light modulated by said artery; a light detector; and a signal processor for determining a distance between the tissue and the probe based on said back-scattered light. A process for determining proximity of a surgical drill bit to an artery during a drilling procedure includes bringing said excitation light near the tissue including the artery; capturing diffused back-scattered light from said tissue; detecting said light modulated by said blood flow dynamics including an oscillating signal related to said periodic change; and processing said light and determining the proximity of the surgical drill bit to the artery.
