SYSTEM AND METHOD FOR ESTIMATING HIGH TIME-FREQUENCY RESOLUTION EEG SPECTROGRAMS TO MONITOR PATIENT STATE

摘要

A system and method for monitoring a patient includes a sensor configured to acquire physiological data from a patient and a processor configured to receive the physiological data from the at least one sensor. The processor is also configured to apply a spectral estimation framework that utilizes structured time-frequency representations defined by imposing, to the physiological data, a prior distributions on a time-frequency plane that enforces spectral estimates that are smooth in time and sparse in a frequency domain. The processor is further configured to perform an iteratively re-weighted least squares algorithm to perform yield a denoised time- varying spectral decomposition of the physiological data and generate a report indicating a physiological state of the patient.
