Spaced Polymark

The Spaced Polymark consists of two Polymark fiducials—crafted from our proprietary, low-density, high-magnetic susceptibility polymer —separated by a bioabsorbable spacer and delivered through a single 18GA-20cm needle.

This configuration reduces needle sticks and guarantees stable, defined spacing between markers. Because the Polymark produces minimal imaging artifact, the Spaced Polymark maintains crisp visibility on CT, kV, CBCT, and MRI—making it an excellent choice for both photon and proton-based treatments.

The result is faster, cleaner setups and greater confidence in demanding IGRT and image-fusion workflows.

Stranded

• Two markers in a single needle reduces needle sticks and decreases procedure time
• Defined spacing aids in proper marker placement and spacing

Visible

• Radiopacity without compromise
• Proprietary polymer easily visible in CT, kV, CBCT, and MRI
• High magnetic susceptibility for MRI visibility

Low Artifact

• Virtually no CT artifact due to low-density, non-metallic polymer
• Will not obscure tissue-tumor interfaces
• Reduced inter-observer variability among Dosimetrists/planners
• Better electron density mapping and dose calculation fidelity
• Improved image registration
• Enables tighter dose conformality in marker-adjacent regions
