Abstract
An 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 conductive traces and copper printed capacitors are carried. The attenuation of the X-Rays caused by the copper 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 of substantially the whole of the RF coil located within the field of view is substantially constant throughout the field of view.
