The XRV-3000 Eagle Beam Profiler combines high-energy radiation detection with precision two-dimensional metrology to form a completely electronic alternative to film-based measurements. The XRV-3000 Eagle measures the XY location and profile of radiation beams with unmatched speed and accuracy. Single beams and proton energy layer patterns up to 30 × 30 cm in size may be directed at the scintillator surface from vertical and horizontal orientations for measurement. Automation scripts can be used to capture changes in the beam shape, intensity, and location over time.
XRV systems calibrate proton and radiosurgery systems or industrial radiation sources that must deliver precise amounts of radiation to targeted regions in 3D space. The correct operation of pencil beam scanning or mechanical leaf collimators used in these systems can be quickly verified. Beam FWHM diameter measurements are accurate to ±0.1 mm and centroid positions to 0.3 mm. Beam viewing software enables real-time any-angle viewing of the captured profile data with live penumbra and symmetry-style measurements. Captured images can be exported to ImageJ or other image analysis software.
All operations are controlled by a laptop or desktop PC supplied with the camera phantom. The XRV comes with a 30 meter (100 feet) USB3 power-over-fiber extender cable so that the system PC and operator can be located safely away from the radiation source. The digital camera phantom weighs approximately 7.0 kilograms (15.5 pounds) and is stored in the Pelican case provided as part of the system.

The XRV phantom may first be imaged with a CT scanner so that the fiducials can be used as a target for the treatment volume. Every beam of the test QA plan can then be measured for delivery accuracy. The XRV technology uses a scintillator to turn the invisible X-rays or protons into a spot of visible light that accurately represents the location and profile of the beam. A sensitive CCD camera then digitizes the beam spot and transfers the bitmap to the XRV computer for analysis and storage.
The BeamWorks Strata software is used to acquire, analyze, and archive XRV images. Beam data is displayed in 3D allowing real-time zoom and viewing angle selection. Beam height, width, penumbra and symmetry measurements are available from any angle of beam rotation. Spreadsheet macros are provided for extended statistical analysis of the captured data. Automated measurements can be made from the graphical user interface (GUI) or customized with an easy-to-use scripting environment.
