A paradigm is presented here, in which the definition of the region of interest center in an MRI scan is automated. This process relies on a probing RF coil, tuned high. A passive RF coil, also tuned high, marks the center of the receive array. As the patient approaches the scan position, and the probing and marker coils come in close proximity, the signal received by the probing coil increases, with the maximum signal obtained when the two coils overlap. We show that precision better than 1cm can be achieved in finding the Rx coil marker using this approach.
