The Gold Anchor, an innovative fiducial marker enables quicker and more effective radiation therapy treatment with increased patient safety.
The unique design makes the Gold Anchor marker easy to implant. The fine 25G, 22G or 20G needle minimize the risk of infection and bleeding, decreases pneumothorax and patient discomfort and enables passage through almost any inner organ. There is no need to use local anesthesia and many users choose to perform dose planning CT of the patients immediately after marker implantation.
Cut-outs in its structure allow the Gold Anchor to be either folded into a "ball" or placed as a "line" during implantation. This guarantees excellent tissue anchorage, reduces the risk of migration or fallouts during treatment and allows more reference points to be achieved with a smaller amount of Gold Anchors.
With a diameter of only 0.28 or 0.40 mm, a much larger surface-to-volume ratio is achieved than with traditional markers. This improves visibility while reducing unwanted imaging artifacts.
Its gold alloy with 0.5% iron content increases visibility in MRI, making the Gold Anchor visible in all common imaging techniques.
The Gold Anchor Fiducial Marker utilizes for the implantation thin 25, 22 or 20 Gauge needles with the following advantages:
Multiple cut-outs allow the Gold Anchor to fold in different shapes depending on implantation technique. This provides a great initial tissue attachment. Line shaped markers are useful for detecting plastic deformations and tilting. Completely folded markers are suitable for systems with automatic marker detection. The initial stability of the Gold Anchor allows the dose planning immediately after implantation.
The Gold Anchor is only 0.28 or 0.4 mm thick, which improves the surface-to-volume ratio. An alloy of gold and 0.5% iron allows an improved MR visibility.
