摘要： A medical system is provided. The medical system includes a processing device communicatively coupled to a probe. The processing device operates to cause the medical system receive physiological signals from electrodes of the probe and decompose the physiological signals into near-field component and far-field component by using mutual information from a set of the electrodes. The processing device operates to cause the medical system utilize the near-field components for localizing in time where a wave went under at least one of the plurality of electrodes.
