Top Radiation Therapy Products


Scan. Analyze. Monitor. Document. As simple as that. BEAMSCAN® comes with a powerful, feature-rich software that makes it easy for you to collect, analyze, process and format your beam data the way you need it. Select from ready-to-use, TPS-specific task lists and perform multiple measurement tasks in one go. Export the results to the optional Track-it QA database to track machine performance over time and document the results as required, in less time.


No tools. No tank shifts. No manual adjustments. Get your BEAMSCAN® ready to scan in a fraction of time using BEAMSCAN® Auto Setup.


There is a faster, easier way to level the water tank. Align the scanning axes virtually – without moving the tank or scanning arms.


Enjoy true Wi-Fi connectivity. BEAMSCAN® is the first 3D water phantom worldwide to include wireless operation and data transfer.


BEAMSCAN® combines speed and precision. With its automated setup and faster scanning speeds, BEAMSCAN® cuts commissioning time in half.
