The XRV family of 3D X-ray beam inspection systems combines precision metrology with high-energy radiation detection to form a completely electronic alternative to film-based measurement. The XYZ location and vector of pencil-thin beams of radiation can now be measured with unmatched speed and accuracy. Beam vector, profile and divergence can be obtained in second rather than hours. Automation scripts can be used to record changes in the beam shape, intensity, location, and direction over time for use in 3D volumetric radiation analysis. XRV systems calibrate stereotactic radiosurgery systems that must deliver precisely dosed amounts of radiation to irregularly shaped volumes. The correct operation of mechanical leaf collimators used in these systems can also be quickly verified before, during, or after treatment. Beam measurements are accurate to .2 mm and measurement repeatability is typically .02 mm. Vector and beam viewing software enables real-time any-angle viewing of the captured data. All operations are controlled by a laptop or desktop PC supplied with the detector phantom. The XRV comes standard with a 19 meter (54 feet) USB cable system so that the system PC and operator can be located safely away from any secondary radiation. The detector phantom weighs approximately 8 kilograms (17 pounds).

XRV Operation The XRV phantom is first imaged with a CAT scanner so that the fiducials can be used to locate the test QA treatment dose. Every beam of an isocenter treatment plan can then be measured for delivery accuracy. The patented XRV technology works on the principle of the hodoscope: the X-ray beam creates entry and exit beam spots on the surface of a scintillator cone located within the phantom. A sensitive CCD camera digitizes the beam spots and transfers the bitmap to the XRV computer for reconstruction into a 3D vector and profile. The WinLVS software application is used to acquire, analyze, and archive XRV images. Beam vector and shape data are displayed in 3D allowing real-time zoom and viewing angle selection. Beam widths can be measured at any vertical slice of the beam. Captured data can also be sent to spreadsheet applications in a Comma Separated Value format. Measurements can be made from the GUI or automated with an easy-to-use scripting environment. Shown above is a representation of X-ray beams striking the XRV-100 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. Thank you for viewing our website.
