Follow the beam: electrons are accelerated, bent toward the patient, and converted to a therapeutic photon beam. Hover any component for details.
Electron beam (accelerated, bent)
Photon beam (after target, divergent)
Beam-line components
Hover (or tap) any labeled component to see what it does.
⚠️ Educational purpose only. This is a simplified, schematic cross-section of a
C-arm photon/electron linac (Varian-style 270° bend). Real machines vary in geometry — some use
in-line waveguides with no bend, and component order/shape differs by vendor. Not for clinical or
service use. | Updated June 2026 | Version 2.0
