An phased array RF coil used for MR imaging is designed so that it remains in place in the field of view of an X-Ray imaging system and comprises a support board on which copper or aluminum conductive traces are carried. The attenuation of the X-Rays caused by the traces is visible in the radiation image but this is compensated by arranging the non-conductive material of the support board such that the attenuation is substantially constant. The phased array includes individual coil loops which are overlapped with the traces being of half thickness at crossing locations of the traces and with one of the loops on one side and the other loop on the second side of the substrate sheet.

In a MRI system housed within a room there is provided a movable magnet and additional components for other procedures on the patient, a control system is provided for the relative movement of the magnet and components. This includes a plurality of magnetic field sensors mounted on the components for measuring the magnetic field at the location of the component and an optional camera positioning system so that the control system can estimate relative positions of the components relative to the magnet from the sensed field strengths from the set of sensors to avoid collisions during the movements.
