OCTAVIUS Detector 1500

Key Features

  • Detector Array with 1405 ionization chambers
  • Gold standard ionization chamber technology avoids detector ageing effects
  • Patient plan verification and machine-specific QA in one system
  • Suitable for use with OCTAVIUS 4D system – the modular phantom for IMRT, VMAT and SRS/SBRT
  • Suitable for a wide energy range including FFF beams
  • Detector spacing: 7.1mm center-to-center
  • Large field size: 27x27 cm²
  • Reproducible, quick and easy positioning with the Couchfix Positioning Tool

Gold Standard ionization chamber technology

  • Compared to diode detectors or solid state detectors, ionization chambers guarantee the following benefits:
  • A long lifetime of the detector
  • No recalibration necessary due to its stable and reliable signal even with accumulated dose
  • Water-equivalent measurements
  • Measurements with a well-established system
  • An excellent field coverage due to its finite ionization chamber size

Verification of very long radiation fields with VeriSoft

The OCTAVIUS Detector 1500 is particularly suitable for complex treatment plans with very long radiation fields.

With its large field size of 27 x 27 cm² it will cover the most treatment plans. If a larger field size is necessary, increase your verification length with the VeriSoft “Compose” feature. Compose two measurements and thus increase the length of your OCTAVIUS Detector 1500 to 48 cm.

True TPS independent QA with full coverage of clinically relevant regions

The measurement principle of the OCTAVIUS Detector together with the OCTAVIUS 4D is the only TPS indepent 3D dose verification system that allows dose to be measured throughout the entire phantom volume and not only at isolated points. This ensures full coverage of clinically relevant regions such as target volumes and organs at risks and the detection of clinical relevant errors.
