State-of-the-art image guidance tool for Proton Treatments
- The ultrathin 0.28 mm line shaped Gold Anchor markers cause very low dose perturbation.
- The high density material provides good visibility on kV imaging.
- The unique and patented gold-iron alloy enhances the MRI visibility.
The CT and MRI images show a line shaped 0.28×10 mm MR+ marker implanted in the prostate.

The film measurements show dose perturbation for a Gold Anchor implanted with a line/zig-zag shape vs. regular gold markers.
Dose perturbation downstream of the markers with the markers oriented perpendicular to the beam axis near the end of the SOBP (Spread-Out Bragg Peak). The doze is normalized to an unperturbed region.
