OCTAVIUS Detector 1500
Advanced IMRT / VMAT QA.
The OCTAVIUS Detector 1500 is a new concept of an ionization chamber matrix in a plane for IMRT verification and quality control in radiation therapy. Utilizing ionization chambers avoids radiation defects, the major drawback of solid state detectors. The vented plane-parallel ion chambers are 4.4 mm x 4.4 mm x 3 mm in size, and the center-to-center spacing is 7.1 mm. In total there are located 1405 ionization chambers in a chessboard matrix, providing a maximum field size of 27 cm x 27 cm. The square chamber design offers unique 50 % field coverage. The OCTAVIUS Detector 1500 can be used for IMRT plan verification, Linac QA (with optional MultiCheck software) and online LINAC adjustment (with BeamAdjust software).The OCTAVIUS Detector 1500 can be mounted to the gantry using the Universal Gantry Mount, used together with the octogonal OCTAVIUS phantom or with the OCTAVIUS rotation unit for advanced 3D dosimetry.

Verification of very long radiation fields with VeriSoft
The OCTAVIUS Detector 1500 is particularly suitable for complex treatment plans with very long radiation fields.
Increase your verification length with the VeriSoft "Compose" feature - compose two VeriSoft measurements and thus increase the length of your OCTAVIUS detector array from 26 cm to 48 cm.
Full coverage of clinically relevant regions
The measurement principle of OCTAVIUS Detector together with OCTAVIUS 4D is the only 4D dose verification system that allows dose to be measured not only at isolated points but throughout the entire phantom volume. This ensures full coverage of all clinically relevant regions such as target volumes and organs at risk.
