PEO presents the Sun Nuclear IC profiler as substitute of the water phantom for direct QA on your Elekta linac

IC Profiler is the ionization chamber based solution for direct QA on linac and the perfect substitute for the water phantom. IC Profiler is a complete scanning system for Linac factory testing, field adjustments, service and routine QA dosimetry. The ionization chambers on the X, Y and diagonal axes measure all beam profiles after a single beam delivery.

Since the start of 2009 Sun Nuclear started producing the IC Profiler and is now used by the Elekta engineers for Linac acceptance, maintenance and service. The IC Profiler is an excellent substitute for the water phantom, as Neil McCann (system engineer at Elekta) demonstrates in a comparison ( <1MB) with the IBA Blue Phantom.

Like all Sun Nuclear products the IC Profiler is easy to use. Analyzing with the advanced PROFILER software is simple and it is also possible to import water phantom measurement data for comparison.


  • total beam QA within 30 minutes
  • solid state, ion chambers, no moving parts (or water)
  • lightweight singular unit design and durability
  • high speed acquistion of field profiles
  • high speed data aquisition – fast set-up of radiation field
  • a measurement provides multiple parameters;
    • flatness
    • symmetry
    • field size
    • beam center
    • penumbra width
    • light: radiation coincidence
  • applications:
    • beam constancy
    • bundle steering
    • diagnostics
    • collimator and rotational sag QA
  • accepted and proven for clinical use and factory acceptance
  • Sun Nuclear universal cable for data and power


  • 32 cm X and Y length and 45 cm diagonal length
  • narrow chamber design of 2,9mm width minimizes ‘dose volume averaging’
  • measures pulse and dose rate every 150ms
  • updates with very low signal/noise rate of 0,15%
  • high dose rate limit >6000cGy per minute
  • weighs only 7kg
  • Start/Stop button for simple measurement control
  • Sun Nuclear universal cable for data and power
