Reference Detector

Interference-Free Dosimetry Scanning

Sun Nuclear's Reference Detector is a patented out-of-field detector that uses linac head leakage to obtain a reference signal during water tank scanning of photon energies.



Features & Benefits

  • Used for beam scanning (commissioning and annuals)
  • Compatible with 3D SCANNER™
  • Eliminates shadowing and interference in-field detectors can cause
  • Ideal for small SRS fields, but can be used for any field size; no need to move location for different field sizes 
  • Parallel plate design
