- 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, OCTAVIUS 4D is completely independent of environmental settings and 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 detector arrays 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. Based on this measurement principle, OCTAVIUS 4D 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 dose 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 and 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 including also special applications like verification of treatment plans with non-coplanar beams, verification of large fields, verification of extremely off-axis lying target volumes or verification of treatments with multiple energies etc. - 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. Through intelligent merging of consecutive dose measurements very long radiation fields, such as typically encountered in craniospinal treatments, can be verified with OCTAVIUS 4D, up to field lengths of even 48 cm. - Powerful evaluation platform
OCTAVIUS 4D’s user interface VeriSoft provides powerful 3D dose comparison and evaluation tools necessary to verify IMRT, VMAT or SRS/SBRT treatment plans. 3D Gamma analysis, DVH analysis in patient anatomy, Profile and dose distribution overlays, Dose-difference distributions, to name just a few. - 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.

Powerful Evaluation Tools
3D Gamma Volume Analysis
Gain more confidence in the accuracy of your results by performing a volumetric 3D gamma index analysis that expands the analysis range from a plane to a volume.
By calculating the gamma value for each voxel in the entire phantom volume and providing the results within less than a minute, the unique 3D volume analysis tool takes the commonly used gamma evaluation one step further. It not only improves passing rates, particularly in regions of steep dose gradients, but also significantly increases evaluation efficiency.
Evaluation in Patient Geometry
Failed points, measured isodoses, contours of the CTV, PTV and organs at risk can be overlaid onto the patient’s CT image, making it easier for you to immediately detect dose errors and identify the possible causes for failures.
DVH 4D Analysis
Optimize your treatment plan based on additional, independently acquired dose data.
Unlike other QA devices, DVH 4D calculates patient dose-volume histograms truly independently of the TPS, entirely based on OCTAVIUS 4D measurement data and the patient’s anatomy, using density values from the patient’s CT scan.
An Integrated Solution
Track, trend and monitor
Track the quality of your treatment plans to take action when needed. Define and assign classes in VeriSoft, e.g., depending on the treatment type (prostate, H&N, etc.), and export the verification results, along with the project file and graphics, to Track-it for efficient case-related monitoring of your QA data in one place.
