A new handy way to improve your Particle Therapy QA

        are you
        ready for the
      future?

All-in-one and accurate device to speed up your QA procedures

nextQ is the unique beam profile measurement device in its new smart and catchy design. It is the new all-in-one device, designed to be both light and robust with its aluminium case.

Where?

nextQ is conceived to be placed at the isocentre and measure the principal beam parameters:

  • position
  • shape
  • intensity

It can be placed facing horizontal line or laid down for vertical lines.

Your essential X and Y beam measurement detector for all particle beams

When?

nextQ is perfect both for QA procedures and commissioning tests.
It allows for the acquisition of the beam parameters with one single beam shot.
Thanks to its new fixing holes, nextQ is suitable to be mounted at the isocentre on every docking station or even on gantry mechanical support.

Who?

nextQ is aimed at all medical and accelerator physicists who require a fast, reliable, compact device.
It is ideal for pencil beams of protons and carbon ions, thanks to its high resolution spot measurements..

Ideal for scanned beams and machine commissioning

How?

nextQ is composed by X and Y strip ionization chambers to measure the beam profiles and two integral chambers for redundant particle flux measurements.
It is very easy and fast to set up.

Why?

nextQ is the new all-in-one device that includes dedicated software, power supply and electronic interfaces inside the detector. These features guarantee both a better signal to noise ratio and a more comfortable set up.
It is a unique device in the market. It is precise, fast and handy to check beam parameters in particle therapy.
