Clinac 21EX/23EX and Platinum Linear Accelerator

High performance, Maximum efficiency.

Clinac 21EX/23EX and platinum

Clinac® EX linear accelerators are high-performance systems with:

  • An instant beam-on with dynamic treatment control
  • The greatest number of energy options to treat the widest range of patients
  • The most precise focal spot size for optimum portal imaging
  • The highest dose rates across the energy spectrum for greater throughput

These capabilities, combined with optional integrated Varian® multileaf collimation and electronic portal imaging systems, enable clinicians to perform the most advanced computer-driven intensity-modulated radiation therapy (IMRT) treatments, as well as conventional therapy techniques.

Features and Capabilities

Standard Features:
  • Two selectable photon beam energies
  • Selectable dose rate up to 600MU/min
  • Choice of electron energies to meet clinical needs, with electron applicators included
  • Tight isocenter alignment of the gantry, couch, collimator, and imagers
  • Reproducible, stable, and accurate machine positioning
  • Exact® couch for accurate reproducible patient positioning
  • Modes for special clinical procedures, e.g. high dose total skin electron mode and total body X-ray mode
  • Enhanced dynamic wedge saves time and the need to reenter the treatment room
  • Auto field sequencing
  • Dynamic procedure modes for photon arcs
  • SmartConnect® remote access technology provides access to Varian® customer support expert assistance and online remote analysis
Optional Features:
  • MLC - the widest range of multileaf collimator (MLC) resolution choices on the market
  • Real-time Position Management™ (RPM) system for respiratory gating system
  • PortalVision™ - megavoltage imaging with optional Portal Dosimetry
  • On-Board Imager® kV imaging system (OBI) - high-quality, low dose imaging for verification and repositioning of patient prior to treatment
