4D in Motion

Why OCTAVIUS®  4D is simply
your best choice for 4D IMRT QA

1. Always top-notch technology

PTW is a pioneer in dosimetry, known to spur innovations that later become an industry standard. With the rotating OCTAVIUS 4D, PTW takes you to a new dimension of patient safety and clinical efficiency. OCTAVIUS 4D is the first and only 4D dose verification system which allows to measure the dose inside the entire phantom volume, always perpendicular to the beam.

2. Thoroughly versatile

OCTAVIUS 4D is a turnkey solution for 4D dosimetry, providing you with all you need to verify IMRT, IMAT or SRS/SBRT treatment plans, including powerful 3D dose comparison and evaluation tools. A straightforward solution, with no hidden costs, no buts, no ifs. With the optional LINAC QA package or DAVID, a unique system for real-time dose verification during patient treatment, OCTAVIUS 4D offers you the most advanced and complete QA solution - from patient plan verification to dose delivery QA.

3. Your budget's best friend

OCTAVIUS 4D is the only truly modular 4D QA system. It supports a variety of other PTW detector arrays for patient- and machine-specific quality assurance. Enhance or simply upgrade to the next-generation PTW detector as and when needed. Your budget will love it!

4. Efficiency to make your live easier

Nice design is not enough. With OCTAVIUS systems, you can forget about time-consuming commissioning and frequent calibration procedures! Based on an innovative product concept and long-term stable ionization chamber technology, OCTAVIUS 4D is ready for everyday use after installation. One thing less for you to worry about!

OCTAVIUS® 4D - Truly measured, not predicted


"Unlike other commercially available
systems .... the OCTAVIUS 4D system reconstructs a 3D dose distribution from measured data points rather than predicted dose values."
