Abstract

An example method includes obtaining an image of a lead implanted in a patient, the lead including one or more electrodes positioned along a longitudinal axis of the lead and a plurality of orientation markers; determining, in the image, respective locations of the one or more electrodes and respective locations of the plurality of orientation markers; determining, based on the respective locations of the one or more electrodes, an orientation of the longitudinal axis; projecting the respective locations of the orientation markers into a plane orthogonal to the longitudinal axis; and determining, based on a projected location of a first orientation marker of the plurality of orientation markers in the plane and a projected location of a second orientation marker of the plurality of orientation markers in the plane, a rotational orientation of the lead.
