A novel design of an 8-channel radiolucent phased array for MR guided Radiation Therapy is presented. The proposed design exhibits superior MR performance characteristics when compared with the equivalent aluminum design. In addition, the proposed design exhibits a uniform X-ray transparency image with no apparent distinction between the copper and its surrounding substrate. Volunteer imaging was also performed indicating that the proposed structure can be ideal for abdominal imaging.
