Information Technology for Electrophysiological Approach of Recurrent Laryngeal Nerve Identification During Surgery on Neck Organs

摘要

Information technology for electrophysiological approach of recurrent laryngeal nerve (RLN) identification during surgery on neck organs is considered in the paper. This technology consists of 4 main steps: obtaining of information signal as result of stimulation of surgery wound tissues; segmentation of information signal; selecting of the main spectral component of segments of information signal; modeling of distribution of the main spectral component amplitudes for RLN identification. A mathematical model for RLN identification is considered as an interval discrete model that is, the difference scheme. Efficiency of proposed information technology is shown.
