OVERVIEW

  • One system for patient and machine QA
  • 3D dose verification in phantom and patient geometry
  • Rotating phantom - true 3D, true isotropic geometry
  • Modular and scalable – various detector arrays and phantom tops
  • Cutting-edge detector technology based on Gold Standard ionization chambers
  • Verification of treatments including non-coplanar beams, off-axis target volumes or very large fields
  • One system for multiple techniques, including Halcyon
  • Simplified workflow - from measurement to case-related monitoring of QA results with optional Track-it
  • Water-equivalent phantom material – no density scaling artifacts
  • Extended dose rate range for FFF beams – no separate detectors required
  • Full field coverage with 3D Merge for better error detection
  • Simple commissioning process
  • 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 from 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.
  • Chamber plates
    Insert plates for single ionization chamber measurements in OCTAVIUS 4D phantom (Semiflex3D, Semiflex 0.125 cm³, Farmer or PinPoint 3D)
  • Starcheck Detector
    The Starcheck array can be positioned in OCTAVIUS 4D for advanced LINAC QA measurements.
  • Bronze / Silver / Gold Service Contracts for OCTAVIUS 4D

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 histo-grams truly independently from 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 pro-ject file and graphics, to Track-it for efficient case-related monitoring of your QA data in one place. Simply click on the project file to review your evaluation in VeriSoft.
