FOLD DETECTION OF AN IMPLANTABLE ELECTRODE ARRAY

A method includes receiving a measurement set comprising a plurality of measurement values generated using a plurality of electrodes distributed along an elongate structure configured to be implanted in and/or on a body portion of a recipient. The measurement set is indicative of a pose of the elongate structure relative to the body portion. The method further includes generating, in response at least in part to the measurement set, a gradient vector dataset comprising a plurality of gradient vector phase values. The method further includes generating, in response at least in part to the gradient vector dataset, an evaluation of the pose of the elongate structure relative to the body portion.
