Enabling state of the art radiotherapy
Intrafraction Motion Management
Fiducial markers provide clear and consistent reference points for the exact real-time location of the tumour target area. This is particularly important for tumours that might move or shift due to internal bodily processes, for example respiration or digestion.
On-board kV imaging
Modern linear accelerators have on-board kV imaging equipment. This enables image guided radiation therapy (IGRT), using either kV or CBCT. Implanted fiducial markers makes it easy and safe for the medical staff to determine the need for patient repositioning prior to each fraction (interfraction motion management).
Elekta XVI seed match
Some accelerators have software that can be used to automatically identify implanted markers in CBCT and CT. It may then also be possible to capture CBCT with lower imaging dose. Note: Elekta is a registered trademark of Elekta AB.
Varian Truebeam Auto Beam Hold
Varian’s Advanced IGRT & Motion package includes the Auto Beam Hold (ABH) feature. We believe that the combination of Gold Anchor and ABH creates unprecedented opportunities to provide safe and economical radiotherapy with high accuracy and precision.
The ultrathin (0.28 mm diameter) Gold Anchor markers cause very low dose perturbation and low CT-artefacts when they are implanted with a line shape. Our unique high density MR+ marker material makes it visible on MRI and provides good visibility on kV imaging.
Synchrony with CyberKnife and Radixact
Gold Anchor has so far been used for Cyberknife® and Radixact® treatments of lung, liver, pancreas, adrenal gland, and prostate. It is recommended to insert Gold Anchor as a ball shaped or tadpole shaped marker. However, 10 mm Gold Anchor markers can also be tracked when inserted as a line shape marker.
Brainlab ExacTrac Dynamic
Brainlab ExacTrac Dynamic allows for fiducial marker tracking using real-time kV-imaging.
Gold Anchor enables a safer and easier radiation process.
Gold Anchor can be used be used with TomoTherapy® system. The best visibility is achieved by implanting a 0.4x20mm marker (GA200-20-B) with a ball shape.
Gold Anchor MR+ offers great visibility in CT and MR images allowing for reliable and efficient MR/CT fusion.
