VERIQA RT MonteCarlo 3D

3D Dose Calculation with SciMoCa

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 SciMoCa Monte Carlo algorithm. Its dose calculation and beam modelling do not require data from the LINAC or treatment planning system, thus allowing truly independent dose verification calculations. 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.

Why use RT MonteCarlo 3D?

Accurate

Monte Carlo simulations are the most accurate method for dose calculation in radiotherapy treatment planning. With its ability to simulate the physics of photons and charged particles transport through matter, Monte Carlo can accurately compute the dose under almost any circumstances. The advanced algorithm of VERIQA RT MonteCarlo 3D achieves a perfect balance between efficiency and accuracy. It enables dose calculations in the most extreme artificial situations with deviations of less than 2 % compared to general-purpose Monte Carlo codes.

Fast

VERIQA RT MonteCarlo 3D has been particularly designed for fast, accurate dose verification calculations in megavoltage external beam radiotherapy. With its advanced algorithm and unique virtual source modelling, it is superior in speed, maximizes efficiency and minimizes non-Gaussian noise. VERIQA RT MonteCarlo 3D comes installed on a powerful server, allowing for very fast dose computations: Calculation results are available in less than 3 minutes.* Due to the streamlined workflow, calculations run in the background – no user interaction required. (* under common clinical conditions)

Integrated

RT MonteCarlo 3D is a fully integrated module of the VERIQA patient QA platform, which automates workflows and streamlines all operations, requiring minimum user interaction. Triggered by the transfer of treatment plans to VERIQA, RT MonteCarlo 3D knows what to do and will take care of all tasks – from calculation and evaluation to notification and documentation. Lean back, relax, and let VERIQA RT MonteCarlo 3D do the work for you.

Independent

Due to its sophisticated beam modelling process, which is based on water phantom measurements, VERIQA RT MonteCarlo 3D performs truly independent dose calculations for a reliable secondary plan check.

„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.
SciMoCa was born from the belief that we can master this challenge for every customer.“
