Fiducial frame and support device

A system comprising:

• a fiducial frame, the fiducial frame comprising:
• a first radiolucent panel located at a first side of the fiducial frame, and a second radiolucent panel located at a second side of the fiducial frame, wherein the first radiolucent panel comprises a first plurality of fiducial positioning markers, and a first identifying marker having a first asymmetric position relative to the first plurality of fiducial positioning markers, wherein the second radiolucent panel comprises a second plurality of fiducial positioning markers, and a second identifying marker having a second asymmetric position relative to the second plurality of fiducial positioning markers, and wherein the first asymmetric position relative to the first plurality of fiducial positioning markers is different from the second asymmetric position relative to the second plurality of fiducial positioning markers;
• and
• a support device, the support device comprising:
• an attachment member for attachment to the fiducial frame;
• and
• a clamp formed of a radiolucent material, wherein the clamp is configured for attachment to a patient support surface, and wherein the attachment member is mounted to the clamp.
