ProBeam® Multi-Room Proton Therapy Solution

Proton therapy is at the forefront of cancer care today. All of Varian's ProBeam® proton systems deliver the most sophisticated type of proton therapy currently available: intensity-modulated proton therapy (IMPT) delivered by pencil-beam scanning.

Here are some of the major components of Varian's proton systems:

ProBeam Multi-Room Proton Therapy Solution


  1. Patient Treatment Room
    The sophisticated patient-positioning system moves in every direction.
  2. 360° Rotating Gantry
    The gantry rotates 190° in each direction, offering 360°  treatment rotations around the patient. This allows for treatment at any angle while minimising the need to reposition the patient. It is easier for the patient, and allows for faster, more efficient treatment times than the other proton-delivery solutions.
  3. Beam-Transport System
    The ProBeam beam-transport system focuses and shapes the beam and guides it to the treatment room, creating the small beam size that is necessary for the IMPT, and this enables the clinicians to target very small spots across the full energy range 
  4. Superconducting Cyclotron
    The isochronous superconducting cyclotron uses electromagnetic waves to accelerate the proton beams.
