OCTAVIUS 4D
Modular Solutions for 3D Patient and Machine QA
OCTAVIUS 4D is an ideal system for routine Patient and Machine QA of all major radiotherapy techniques – from conventional step-and-shoot to multiple-arc, non-coplanar treatment plans. With its modular phantom design and a variety of detectors, OCTAVIUS 4D allows you to select the phantom and detector combination that is best for your patient QA needs. Today and tomorrow.

- Full range of advanced comparison and analysis tools for a clinically relevant dose analysis
- Completely independent QA
OCTAVIUS 4D requires no data input from plan/linac for measurement and 3D dose reconstruction. A simple set of PDDs measured in water – that’s all! Unlike other commercially available systems, it is completely independent of environmental settings. It guarantees maximum reliability in Patient QA procedures.
- Truly modular
OCTAVIUS 4D is the only truly modular 4D QA system. It supports a variety of PTW array detectors and phantom tops for efficient patient- and machine-specific quality assurance.This allows matching the measurement setup according to the particular clinical situation. And extends the scope of OCTAVIUS 4D significantly.
- Unique measurement principle – Fully transparent
OCTAVIUS 4D measures dose time- and angle-dependent. It ensures perpendicular irradiation of the PTW array detector through synchronous phantom rotation with the linac gantry. It is the only 4D dose verification system which allows measuring the dose. Not only at the isocenter or the phantom’s surface but also inside the entire phantom volume. Without applying any non-transparent response corrections.
- Minimum commissioning efforts
Compared to competitor products, OCTAVIUS 4D needs no time-consuming commissioning process. A simple set of PDDs measured in water at different field sizes is the only input. This can either be taken directly from already existing basement data or from freshly performed water phantom measurements.
- Extended application range
Besides standard VMAT or IMRT deliveries, OCTAVIUS 4D covers a wide range of clinical applications.
Special applications too, like:
– verification of treatment plans with non-coplanar beams
– verification of large fields
– verification of extremely off-axis lying target volumes
– verification of treatment plans with multiple energies - Virtually FOV extension
In some clinical situations the dimension of the target volume cannot completely be covered by the field of view (FOV) of the OCTAVIUS detector. Therefore, with OCTAVIUS 4D very long radiation fields (like in craniospinal treatments) can be verified up to field lengths of even 48 cm using intelligent merging of consecutive dose measurements.
- Powerful evaluation platform
OCTAVIUS 4D’s user interface VeriSoft provides powerful 3D dose comparison and evaluation tools like:– 3D Gamma analysis
– DVH analysis in patient anatomy
– Profile and dose distribution overlays
– Dose-difference distributions.
These are necessary to verify IMRT, VMAT or SRS/SBRT treatment plans. - Case-related data management
Connected to PTW’s data management platform Track-it retrospective data analysis and trending of Patient & Machine specific QA data points out performance changes over time.
