Abstract
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.
