BiomarC Fiducial Markers
The gold standard is no longer gold.
Metallic fiducial markers tend to overly artifact in CT, can be difficult to see in MRI, and can perturb the beam making them inappropriate for proton therapy applications. The BiomarC line of fiducial markers consists of a low density zirconium-oxide ceramic core sheathed in a pyrolytic carbon coating. This unique combination provides a marker with the following properties:
BiomarC is very easily visible in MRI due to the superb electric insulating properties of ceramics.
BiomarC has an extremely low density, dramatically reducing CT artifact and beam perturbation.
BiomarC has the exceptional biocompatibility of carbon.
