PROFILER Family

The Industry Standard

  • Full-field real-time measurements
  • Quick and easy setup
  • Measure at isocenter for any gantry angle


The Industry Standard

Every clinic should have a PROFILER. The extended PROFILER family delivers fast and powerful beam QA at thousands of clinics, as well as Linac manufacturing facilities and Linac service groups. PROFILER provides a wealth of information about beam performance in real-time, and takes only minutes to setup. It’s that simple, and that powerful.

Real-Time Machine QA,Commissioning and Trouble Shooting

The PROFILER family of 2D arrays share a common mission: real-time precision measurements for a wide variety of routine QA, commissioning, and troubleshooting applications. Each PROFILER model is designed for maximum flexibility within a specific application, although each is useful across many applications.

Routine QA

Use instead of a water tank for high resolution routine QA of many parameters

Commissioning

Real time measurements of modulated fields such as electronic wedges; export to planning system

Trouble Shooting

Highly flexible real-time measurements allows for trouble shooting of beam and linac anomalies, and verification testing after Linac service and parts replacement
