Instant Stability That Makes You Trust Each Fiducial Marker • Gold Anchor

Instant stability

Anchors immediately

placeholder

Multiple cut-outs allow the fiducial marker to fold (Int. patents)

The fiducial marker is passive and will form different shapes depending on implantation technique.

Line shaped markers are useful for detecting plastic deformations and tilting.
Completely folded markers are suitable for systems with automatic marker detection.

Anchors directly

Gold Anchor gets a great tissue attachment when the marker folds. The ball shaped marker becomes thicker than the needle tract and that prevents the marker from migrating in the needle tract when the needle is withdrawn.

Even as a line shaped marker the cut-outs in the Gold Anchor marker ensure a strong tissue attachment. The flexibility of the marker also allows it to absorb tissue deformation effectively.

Trust each marker

The stability of the marker in the tissue can also be verified by comparing the marker shape over time. One Gold Anchor marker can therefore be sufficient in selected cases where corrections for rotation and tilting are not performed. Preserved shape acts as a proof of no migration.

At treatment

Use fewer fiducial markers

1 Gold Anchor

Enables adjustment of translational setup errors (X-Y-Z).

2 Gold Anchors

Enables adjustment of translation and rotation provided that at least one of the markers is implanted with a line shape, which also makes it easier to distinguish the two markers from each other in the lateral view.

3 Gold Anchors

Enables adjustment of translation and rotation. Ideal for registration of CT and MR images.

Note: Traditional fiducial markers are more likely to migrate and many centers therefore implant at least three traditional fiducial markers to be able to detect if any of those markers have moved (by looking for a potential change in the distance between the markers).

Save lead time and travel

With Gold Anchor there is no need wait the usual 7-21 day before dose planning. The thin Gold Anchor needle, that causes minimal bleeding and swelling, in combination with the strong tissue attachment of the marker, makes it possible to proceed with CT and/or MR for dose plan on the same day as implantation.

Note: Most centers that use traditional markers send their patient home for 7-21 days after implantation to allow the traditional markers to “settle in”, i.e. to allow the potential bleeding and swelling subside to reduce the risk that the traditional markers migrate in the tissue.

“Since incorporating The Gold Anchor into my practice, we have been able to treat patients with an increased level of efficiency, safety, and accuracy. Its thin needles allow for a more tolerable fiducial marker, which has led to significantly lower infection rates post placement.

The unique design minimizes migration after placement, which leads to consistent CT imaging as treatment continues. All of this allows for quick and accurate care.”
