VERIQA RT MonteCarlo 3D
3D Dose Calculation with SciMoCaTM
Accurate. Fast. Automated.
Monte Carlo techniques are the gold standard for dose calculation in radiotherapy. VERIQA RT MonteCarlo 3D calculates dose using the well-known, clinically proven SciMoCaTM Monte Carlo algorithm. VERIQA is independent of LINAC vendors and treatment planning systems, thus allowing a truly independent dose verification calculation. Calculation results are not only highly accurate, but also available in a few minutes.
As part of the VERIQA patient QA platform, VERIQA RT MonteCarlo 3D offers fully automated dose verification. By combining speed and accuracy, it can help you to enhance safety as well as increase efficiency in daily patient QA.

In addition to 3D-dose calculation, VERIQA RT MonteCarlo 3D provides a Monte Carlo based MU and point dose verification per beam.
If the 3D-evaluation leaves room for uncertainty, the 1D-evaluation offers the possibility to revert to the established MU-based check.
For each treatment plan, VERIQA automatically provides the per beam dose and MU information in the dose specification point defined in the TPS, with no additional effort for the user.
„VERIQA is a powerful QA platform which easily enabled us to implement a fully automated secondary Monte Carlo dose calculation for every of our patients.
The excellent accuracy and reliability of RT MonteCarlo 3D allowed us to reduce the amount of plan-specific phantom measurement by 75% - without compromising the quality and safety of our patient treatment.”
Dr. Bernhard Rhein, Medical Physicist, Heidelberg University Hospital

„In practice, Monte Carlo dose calculation is only as accurate as the specific beam model for the customer´s linac.
SciMoCaTM was born from the belief that we can master this challenge for every customer.“
