VMAT/IMRT patient plan verification software with advanced tools for measurement, dose comparison and evaluation.

VeriSoft supports the control of all available PTW OCTAVIUS solutions necessary to verify IMRT, VMAT or SRS/SBRT treatment plans. Integrated dose reconstruction algorithms support OCTAVIUS 4D for verification of standard and non-standard clinical parameters such as non-coplanar beams, large fields, extremely off-axis lying target volumes or treatments with multiple energies etc.

VeriSoft provides powerful 3D dose distribution comparison and evaluation tools needed to answer the question “Does the patient plan agree with my acceptance criteria?” with full confidence. In addition to all standard comparison tools VeriSoft gives you a full  range of advanced tools for the comparison in axial, sagittal and coronal planes.

Key Features

  • Composite or Control Point Analysis
    • To analyze details either the complete plan or user-defined gantry angle segments ("Control Points") can be loaded for dose comparison.
    • 3D Gamma Index Analysis
      VeriSoft enables calculating not only the 2D but also 3D gamma index for each of the three planes (axial, sagittal, coronal), which may reduce the number of failed points in high dose gradients. If local dose is chosen as gamma evaluation criterion, overdosage in low dose regions can be detected which may be overseen when using the maximum dose level as reference value.
    • 3D Volume analysis
      A volumetric 3D gamma index analysis expands the analysis range from a plane to a user-defined volume. It not only improves passing rates, particularly in regions of steep dose gradients, but also gives the user a complete picture of the gamma result in the entire phantom volume, which significantly increases evaluation efficiency.
    • Patient CT overlay
      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 to detectdose errors immediately and identify the possible causes for failures.
    • Independent patient-based DVH analysis
      Unlike other QA devices, DVH 4D calculates patient dose-volume histograms truly independent from the TPS, entirely based on OCTAVIUS 4D measurement data and the patient’s anatomy, using density values from the patient’s CT scan.
  • VeriSoft Projects
    Evaluations can be saved as “Projects” in VeriSoft, which contain all settings and data required to resume or review patient-related analysis results in VeriSoft at a later stage.
  • Case-related data management of verification data
    VeriSoft allows to evaluate verification data depending on user-defined criteria like for instance type of treatment (e.g., prostate, head & neck, etc.), treatment technique (VMAT, IMRT, SBRT, etc.) or photon energy (6MV, 10MV FFF, etc.). Connected to PTW’s data management platform Track-it, retrospective data analysis and trending of these patient specific QA data point out performance changes over time.
