Refractory Metals for Medical Technology
Radiation therapy and X-ray diagnostics demand materials that shield or generate high-energy radiation in the tightest of spaces — without failing themselves or putting the patient at risk. Steel or lead reach their limits here in density, dimensional accuracy or biocompatibility.
Which Material for Which Function
Tungsten Heavy Metal
Very high density without the toxicological drawbacks of lead: collimators, multileaf shutters and radiation shielding in CT, X-ray and linear accelerator systems.
Molybdenum
High thermal-shock resistance under electron bombardment: anode discs in X-ray tubes.
Tantalum
Proven biocompatibility and corrosion resistance inside the body: implants and surgical instruments.
Niobium
Biocompatible and non-magnetic: implant components that must remain MRI-compatible.
Components in Everyday Use
- Multileaf collimators for linear accelerators
- Radiation shielding shutters in CT and X-ray systems
- Anode discs for X-ray tubes
- Counterweights in C-arm systems
- Implant components
- MRI-compatible markers
