AI Technical Summary

Technical Problem

Existing technologies struggle to accurately locate the source of oscillatory signals within the brain, limiting the precision and effectiveness of electrical stimulation therapy.

Method used

By comparing the actual measurement results of the electrical signal with the expected measurement results, the hypothetical position of the oscillation signal source is iteratively adjusted using a regression formula until the error value is less than the threshold, thus determining the accurate position of the oscillation signal source and selecting the most suitable electrode for treatment delivery.

Benefits of technology

This improves the precision and effectiveness of electrical stimulation therapy, ensuring that the electrode selection matches the location of the oscillating signal source, thus enhancing the therapeutic effect.

Abstract

This invention describes a technique for determining the location of at least one oscillating signal source within a patient's body. A processing circuit can determine a desired electrical signal level based on the hypothetical location of the at least one oscillating signal source. The processing circuit can determine the electrical signal level and, based on these desired electrical signal levels and the determined electrical signal level, determine an error value. The processing circuit can adjust the hypothetical location of the at least one oscillating signal source until the error value is less than or equal to a threshold, including examples where the error value is minimized.
