OCTAVIUS® Detector 1500 MR

Array Detector for Linac and Patient QA at MR-Linacs

The OCTAVIUS Detector 1500 MR is a new concept of an ion chamber matrix in a plane for IMRT verification and quality control in MR guided radiotherapy.

Key Features

  • Suitable for use with OCTAVIUS 4D MR – the modular QA phantom
  • Active volume 4.4 mmx 4.4 x 3 mm3 per chamber
  • Detector spacing 7.1 mm center-to-center
  • Large field coverage: 27 cm x 27 cm
  • One single device for linac and patient-specific QA
  • Gold standard ionization chamber technology avoids detector ageing effects
  • Also suitable for IMRT plan verification
  • Outstanding detector and matrix design: 1405 vented ionization chambers
