Gold Anchor™ marker for IGRT, a new fiducial for high-precision radiotherapy

Conclusion: Increasingly, we must be certain of exact localization of tumor targets by using markers and IGRT. The fine-needle marker presented here allows implantation into almost any tumor site with minimal risks of internal bleeding, infection or pneumothorax and can be implanted safely and precisely using guidance with ultrasound or CT. The Gold Anchor™ is […]

An assessment of inter and intrafraction prostate mobility using Gold Anchors during prostate cancer patients volumetric modulated arc radiotherapy (RapidArc)

Conclusion: The patient positioning using 2D/2D kV and Gold Anchors increases the setup precision and enables to reduce margins. Because the prostate motion during the course of radiotherapy can be significant, margins for the PTV should include the intrafraction prostate mobility. Poster at ESTRO 2010, poster #1674

Using Foldable Gold Anchor Markers for Fiducial Tracking with the CyberKnife

Conclusion: It is feasible to use gold anchor marker for Cyberknife. Ball shape or Tadpole gold anchor markers are recommended. Visual confirmation of lock-on is important due to the irregular shape of gold anchor markers. More study is needed to evaluate clinical effect.

Comparison of the SBRT frame procedure versus Gold Anchor fiducial marker IGRT on Accuracy, Precision and Economy

Conclusion: Positioning of the target with orthogonal images or CBCT with the Gold Anchor fiducial marker insertion is intuitive and easily accomplished for safe positioning. Excellent accuracy and precision can be achieved without the need of positioning patients in stereotactic whole body frames. The total cost of treatments with the Gold Anchor technique is less […]

Assessment of stability of Gold Anchor™ fiducial marker implants in the prostate

Conclusion: The position of the Gold Anchor™ fiducial marker in the prostate gland is stable, the marker remaining within the gland volume. The period of marker stabilization is less than the 7 days recommended by the manufacturer. We suggest that virtual simulation of the patient can be performed immediately after marker implantation.

Spatial Accuracy and Visibility Studies of a MRI Compatible Gold Anchor™ Fine Needle Fiducial Marker

Conclusion: The new MRI compatible Gold Anchor™ adds new features on top of the existing advantages. For specific anatomical targets treatment planning with fiducial marker information can be performed based only on MR images. For other targets images from both MRI and CT can be matched through the information from the fiducials. The content of […]
