BEAMSCAN Software 4.5


All-in-One or Separate

Which BEAMSCAN® model is best for you?


  • Space saver

    If your treatment room is small or adequate storage space is not available, an all-in-one solution may be the best choice for you.
    As an all-built-in-system, BEAMSCAN® comes on a single, easy-to-move lift carriage, including everything needed - from tank to water reservoir. Compared to BEAMSCAN® Duo, it offers a much smaller footprint which makes it ideal for facilities with limited space.
  • Ease of installation

    As an all-in-one system, BEAMSCAN® is ready for use whenever you need it. Its superior ease in setup and general day-to-day use is a huge advantage and time saver. No need to make two trips to the storage room or ask your colleague for assistance.
    If you look for maximum comfort and efficiency, then BEAMSCAN® would be a wise choice.


  • Weight saver

    Narrow hallways, ramps, uneven flooring or small doorways may be more difficult to navigate with a combined carriage.
    By splitting the weight on two carriages – a lift and a water reservoir carriage –, BEAMSCAN® Duo can make transport and maneuvering easier if your site conditions are not ideal. The lighter lift carriage also reduces the overall weight on the turntable.
  • Ease of handling

    As the water reservoir of BEAMSCAN® Duo comes on a separate carriage, the lift carriage for the water phantom is lighter, which makes it easier to position and align the water tank to the linac.
    With the water reservoir out of the way, the BEAMSCAN® Duo lift table also gives better access to the water tank, e.g., to exchange detectors.
