Exradin® W2 Scintillator System

Exradin® W2 Scintillator System part of complete solution for: Annual QA Stereotactic

Exradin® W2 Scintillator System Overview

  • AAPM/IAEA TRS 483 states the scintillator is the only detector with a kQ of 1.000, making the W2 the ideal SRS detector.
  • All corrections are built in.
  • Water equivalent.
  • Inherently waterproof.
  • Can be used for both water scanning and point dosimetry.
  • User replaceable fiber, includes both 1x1 mm and 1x3 mm.
  • No dose rate, temperature, or energy dependencies.
  • The W2 system features Čerenkov corrected measurement signals that can be converted to a proportional analog output, which can be read by any electrometer. This allows the W2 system to be connected to a water phantom system for scanning.
