3D scintillator cone-based systems

These 3D phantoms take the place of the patient on the treatment couch and are used for targeting and dose/fluence delivery testing. They can measure the vector location of the X-ray beam, the beam shape and intensity, and the pointing accuracy of the robot mechanism in real-time.

The XRV-100 has a 60 degree imaging cone that is 12 cm long, giving it a 70 mm long field of view along the center axis. With a vector position accuracy of up to 0.2 mm, it is ideal for measuring the rotational center of a system that uses beam diameters 3 - 30 mm (FWHM) in size.

The XRV-124 has a 45 degree imaging cone that is 24 cm long, giving it a 140 mm long field of view along the center axis, with similar accuracy as the XRV-100. Vector position accuracy is up to 0.3 mm for small beams. This enables the XRV-124 to capture larger beam sizes and fields at a wider variety of angles. The XRV-124 is capable of 3D measurements for beam diameters 4-60 mm (FWHM) in size.

2D scintillator flat-surface systems

These 2D beam profiler phantoms can be used to measure the position and profile of the treatment beam in real-time. BeamWorks Strata is the software program that controls the capture and analysis of beam data. Special features are included for "scanning window" style MLC measurements.

The XRV-2000 Falcon has a flat 20 × 20 cm scintillator. The Falcon comes with an auxiliary stand so that it can be positioned on its side for lateral beams, or it can be mounted in an optional gantry cradle that allows it to be manually turned a full 360 degrees. The scintillator can thus be positioned to be perpendicular to the incoming X-ray or proton beam at any angle of delivery from the treatment system gantry. Fiducials may be placed on the XRV-2000 Falcon target which is located directly over the scintillator surface.

The XRV-3000 Eagle has a flat 32 × 32 cm scintillator. The Eagle comes with an auxiliary stand so that it can be positioned on its side for lateral beams, or it can be mounted in an optional gantry cradle that allows it to be manually turned a full 360 degrees. The scintillator can thus be positioned to be perpendicular to the incoming X-ray or proton beam at any angle of delivery from the treatment system gantry. Fiducials may be placed on the XRV-3000 Eagle target which is located directly over the scintillator surface.

The XRV-4000 Hawk has a flat 42 × 32 cm scintillator. The mirror orientation is fixed to normally measure anterior/posterior beams. The unit comes with an auxiliary stand so that it can be positioned on its side for lateral beams, or it can be mounted in an optional gantry cradle that allows it to be manually turned a full 360 degrees. The scintillator can thus be positioned to be perpendicular to the incoming X-ray or proton beam at any angle of delivery from the treatment system gantry. Fiducials may be placed on the XRV-3000 Eagle target which is located directly over the scintillator surface.
