a logic configured to receive a measurement from one or more radio frequency (RF) sensors arrangeable outside a bore of an MR imaging apparatus, during use of the system and the logic to process the measurement to establish: i) whether there is at least one surface RF coil present that is not electrically coupled to circuitry of the MR imaging apparatus; and/or ii) to localize at least one surface RF coil on or at a patient table of the MR imaging apparatus; wherein the measurement is based on a response signal caused by an RF loop forming the at least one surface coil, the RF loop operable in an imaging operation of the MR imaging apparatus, and the response signal caused in response to a transmit signal transmittable by at least one transmitter.
