RadCalc version 7.4 - New features and highlights

• RadCalc Portal and Services Manager Updates:
  • - Support for 3D electron calculations added to the RadCalc Portal.
  • - The RadCalc Portal is now in now available in English and French.
  • - The RadCalc Services Manager responsible for background execution of RadCalc Portal, RadCalcAIR and the Queue has had installation and operational improvements.

• 3D Electron Dose Calculations:
  • - Added support in RadCalc Classic for 3D dose calculations using the fast Monte Carlo developments, including features such as Dose Analysis, DVH, isodose lines, gamma analysis, and printouts.
  • - 3D dose volumes are integrated into the RadCalc Portal via RadCalcAIR for efficient processing.
     
• Photon Calculations with Fast Monte Carlo:
  • - The new fast Monte Carlo development supports photon calculations for C-arm linacs and Halcyon systems.
  • - Particle count and batch sizes are optimized to enhance statistical reliability of uncertainty calculations. Output consistency is verified against BEAMnrc across multiple uncertainty thresholds.
     
• Rule Updates for Added Automation in Delivery QA Workflows:
  • - Clauses added to distinguish between "in-air" and "in-vivo" FLQA/EPID calculations.
  • - Workflow filtering by treatment planning protocols (TPPs).
  • - DICOM tag–based rule clauses now supported for TPP automation.
  • - Rules to select different algorithms, calculation parameters, gamma criteria and more!
     
• Customizable 3D-only Display Options:
  • - Beam MU/Beam Time and Calculation Points badges can be hidden for plans that have a 3D dose comparison. Hiding point dose information will result in showing only Gamma Analysis, DVH Protocols, and 3D dose point comparisons when selected.
     
• Simplified Monte Carlo Calculation Settings:
  • - Enhanced uncertainty parameter settings for BEAMnrc and fast Monte Carlo to standardize secondary dose checks. The user now defines a range for the uncertainty calculation of Low, Standard, High, or Expedited. The obtained uncertainty and the number of particle histories is reported for each calculation.

• System and modality support
  • - Added support for EPID image processing from TrueBeam v4.1 systems with Acquisition System v5.0.2.109.
  • - Tomotherapy modelling updated: refined leaf geometry, adjusted MLC focal point, and revised point dose computation for improved agreement with plans using the VoloUltra optimization algorithm from Accuray.
  • - Preliminary support for GammaPlan v11.5 database integration.

• Other Photon and Electron Improvements
  • - DICOM tag– Adjusted Varian Millenium 120 leaf MLC and the HD120 MLC BEAMnrc MLC leaf dimensions for improved consistency with measured profiles. The beam model will not need to be re-generated for BEAMnrc customers with these MLCs, however, the ARLFO will need to be re-optimized.
  • - Modified the import for Electron calculations to ensure that only points with valid coordinates are included. It is recommended that Electron plans are exported with the Structure set and RTDose to ensure the correct information is included from the TPS, regardless of any caveats from the different TPS.

The RadCalc Portal supports workflows tailored to different QA needs:

1. SDC-Only Workflow: Evaluate results of secondary dose checks (SDC) performed via RadCalcAIR.
2. In Vivo EPID Dosimetry Workflow: SDC supplemented with in-vivo dosimetry.
3. Pre-Treatment EPID Workflow: SDC supplemented with in-air EPID dosimetry.
4. Comprehensive EPID Workflow: SDC supplemented with both in-vivo and in-air EPID dosimetry.
5. Log File QA Workflow: SDC supplemented with treatment delivery logfile analysis.
6. Full Treatment Delivery QA Workflow: Combines EPID dosimetry workflows and logfile QA for comprehensive analysis.

These workflows can be configured in under an hour with assistance from our customer support team, leaving you ready to refine clinical processes as needed.
