American Radiosurgery produces the new RGS Orbiter ™ that will treat head, neck and spine tumors and the whole body. This unique technology will now allow you to treat tumors that cannot be cured using traditional gamma knife * technology. The RGS Orbiter concept is unique in that it is the first single-fraction Cobalt-60 radiosurgery system for the treatment of lesions outside the brain. The design of the RGS Orbiter facilitates the highest level of operator precision while maximizing optimum patient comfort. The patient is fixed to the treatment table with an immobilization device, preventing patient movement during treatment. In the case of skull therapy, the patient's head is immobilized with a standard stereotactic head frame. This is the same head frame used in the RGS Vertex360.

The machine is equipped with two body fixation frames, one used for patient treatment and the other for imaging. Marking points on the frame provide precise placement as the patient moves from the viewing frame to the treatment frame. Patients do not need to wear the body frame when traveling from the imaging department to the treatment room.

The treatment head accommodates 26 Cobalt-60 sources (230.76 Ci) arranged in a single line on a ± 25 ° circular segment as seen from the isocenter around the patient's length axis when the table is in the home position. Initial resource efficiency is 6,000Ci. The source isocenter distance is 469mm.

The C-arm portal and open space design of the RGS Orbiter is similar to a set of linear accelerator systems. C-arm slide provides welding rotation with a precision of 0.3 - 0.5 mm.

Rotating Gamma System® Vertex 360 ™ (RGS Vertex360) is a special neurosurgical radiosurgery system used in the non-invasive treatment of brain tumors.

The RGS Vertex360 uses concentric, controlled arcs created by rotating gamma ray beams emitted from thirty cobalt-60 sources. The unique design of the RGS Vertex360 excels in combining the accuracy of the static Gamma Knife * design with the beneficial "springs" of accelerator-based systems.

RGS Vertex360 welds are contained in an outer rotating hemispherical shell and arranged in an asymmetrical pattern. Includes a matching inner spinning sphere, a variety of collimator sizes and blocking plugs. A simple switch selection allows the welds in the outer shell and the selected collimator size in the inner shell to match and rotate around the head simultaneously within the shielded machine cavity. This switch selectable technology provides striking advantages that cannot be achieved with the legacy Gamma Knife static design.

The Explorer4D ™ Treatment Planning System is a sophisticated software package that allows visualization of patient anatomy and disease status on a processed three-dimensional display. Treatment scheduling for the RGS Vertex360 ™ and RGS Orbiter ™ is implemented as an add-on to the award-winning OsiriX medical imaging software: The plug-in inherits OsiriX and adds a custom dosing engine to the RGS. All the features of OsiriX are still available to the user. Additional functionality is available via the ARGS (Asynchronous Rotating Gamma System) menu.

Features include:

Create, edit and save treatment plans Automatic registration of reference marker Visualization of isodose lines in 2D and multi-plane views Display of Leksell coordinates and dose at mouse positions Dose Volume Histograms (DVH)
