The XRV family of X-ray and proton beam inspection systems combine precision metrology with high-energy radiation detection to form a fully electronic alternative to film-based measurements. The XYZ location and vector of pencil-thin beams of ionizing radiation can now be measured with unmatched speed and accuracy. Beam vector, profile, and divergence can be obtained in seconds rather than hours. Automation scripts can be used to capture changes in the beam shape, intensity, location, and direction over time for use in later analysis or 3D volumetric reconstruction.

XRV systems verify that the proton and X-ray therapy subsystems (robot, collimator, radiation source, and kV imagers) are working together to accurately deliver radiation to the irregularly shaped lesion volume. Beam position measurements are accurate to 0.3 mm and measurement repeatability is typically 0.03 mm. Vector and beam viewing software enables real-time any-angle viewing of the captured data. Up to 4,000 frames of video can be captured real-time at rates from 1 to 30 frames per second.

All operations are controlled by a laptop or desktop PC supplied with the detector phantom. The XRV comes with a 30 meter (100 feet) power-over-fiber USB cable system so that the system PC and operator can be located safely away from the treatment room. The detector phantom weighs approximately 8 kilograms (17 pounds).Features and Benefits:
