    Pencil-beam scanner

    Our pencil-beam-scanner—the first to be made commercially available—offers precise dosage sculpting up to 2G/L/min, with layer switching in less than one second.

    Spares more healthy tissue

    Careful dose sculpting and tight pencil beams combine to direct treatment where it’s needed and avoid healthy tumor-adjacent tissue.

    Deeper reach

    Deeper, more precise penetration means you can treat tumors that are more complex or further from the surface.

    Unlike many single-room proton therapy solutions, ProBeam’s pencil beam scanner permits intensity-modulated proton therapy (IMPT).
