Abstract
A structural support component such as a head clamp for use in imaging of a part of a patient using Magnetic Resonance and X-ray imaging is formed of different materials each of which has an Aluminum equivalence factor of less than 10 mm and generally less than 6 mm and is arranged such that the presence of the structural support component in an imaging zone of a magnetic resonance imaging system when generating the image does not generate any visually determinable distortion in the image. The materials can be epoxy resin combined with a glass fiber substrate for easily machined parts, polyphenylene sulphide with random fiber reinforcement using glass fibers for high wear parts and polyurethane foam or Polymethacrylimide foam shaped to form a required member and covered on its outer surface with a layer formed from aramid fibers for elongate parts.
