3D Beam Profile Viewing
The XRV family of X-ray and proton beam inspection systems combine precision metrology with high-energy radiation detection to form a completely electronic alternative to film-based measure-ments. 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 record 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 .3 mm and measurement repeatability is typically .04 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 up to 30 frames per second.
Shown above is a representation of X-ray beams striking the XRV-124 scintillator cone from various angles. Once the entrance and exit spots for each beam are measured, the 3D path can be precisely calculated and displayed in the Vector Viewer application below.
