摘要：
Systems and methods for performing current steering compatible image-guided cochlear implant (CI) electrode deactivation. The cochlear implant includes an electrode array having a plurality of electrodes implanted in a cochlea of a living subject. For each electrode, a corresponding distance-vs-frequency (DVF) curve is obtained. An analysis is performed on the DVF curves to identify the interfering electrodes, each having an interference with at least one other electrode. Then, rules may apply to the interfering electrodes in order to select one or more interfering electrodes to be deactivated. The rules may include: keeping the electrode having a corresponding DVF curve located at a left-most location on the plot to avoid a resulting sound frequency upshift； avoiding leaving any electrode stranded without a neighboring electrode； and deactivating a minimal number of the interfering electrodes to ensure that high interference is allowed only for each electrode with one neighboring electrode.
