Abstract: A patient couch for use in a medical imaging system that includes a gantry, a power supply unit and a driving unit for positioning the patient couch with respect to the gantry. The patient couch includes at least a first connector for supplying a wireless coil (e.g., a radio frequency (RF) coil for an MRI imaging apparatus) with power. The patient couch is detachably connected to the gantry. The power supply is configured to supply the first connector with power and an optional clock synchronization signal.
