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

IC Profiler features:

• accepted and proven for clinical use and factory acceptance
• solid state, ion chambers, no moving parts (or water)
• total beam QA within 30 minutes
• high speed acquistion of field profiles
• universal cable for data and power
• 32 cm X and Y length and 45 cm diagonal length
• high dose rate limit >6000cGy per minute
• start/stop button for simple measurement control
• narrow chamber design of 2,9mm width minimizes ‘dose volume averaging’
• high speed data aquisition – fast set-up of radiation field
• multiple parameters: symmetry, beam center, flatness, field size, radiation coincidence and penumbra width
• applications: diagnostics, bundle steering, beam constancy and collimator and rotational sag QA
