Enabling state of the art radiotherapy
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).

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’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 thinner (0.28 mm diameter) Gold Anchor markers cause very little dose perturbation when they are implemented with a line shape. The high density of gold material provides good visibility with kV imaging.
Gold Anchor has so far been used for Cyberknife® 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.
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.
