Electrode position detection

A medical device system comprising:

• stimulation generation circuitry configured to deliver electrical stimulation via a first electrode of a plurality of electrodes;
• and
• processing circuitry configured to control the stimulation generation circuitry to deliver, via the first electrode, an electrical stimulus;
• sensing circuitry configured to sense, for each other electrode of the plurality of electrodes, a respective electrical signal indicative of the electrical stimulus,
• wherein the processing circuitry is further configured to determine, for each other electrode, a respective value for each respective electrical signal, and
• wherein the processing circuitry is further configured to determine, based on the respective values for each respective electrical signal sensed by each other electrode of the plurality of electrodes, spatial relationships between the first electrode and each other electrode of the plurality of electrodes.
