Abstract
A system (SYS) and related method for supporting MR imaging. The system (SYS) comprises a logic (CL) to receive a measurement from RF sensors (SS1-8) arrangeable outside a bore (BR) of an MR imaging apparatus (IA). The logic processes the measurement to establish i) whether there is at least one surface RF coil present that is not electrically coupled to circuitry (SPC) of the MR imaging apparatus (IA) and/or ii) to localize at least one surface RF coil on or at a patient table (PT) of the MR imaging apparatus.
Claims15
A system for supporting magnetic resonance MR imaging, the system comprising:
- a logic configured to receive a measurement from one or more radio frequency, 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 said 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.
A method for supporting magnetic resonance (MR) imaging, the method comprising:
- receiving a measurement from one or more RF sensors arrangeable outside a bore of an MR imaging apparatus, and
- processing 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 caused in response to a transmit signal transmittable by at least one transmitter.
