The 3DRTT Project Goal - Proton Therapy Simulator ... coming soon ...

Simulator 3DRTT is a real-time 3D web-based graphical simulator for radiation therapy linear accelerators. The purpose of the simulator is twofold:

  1. To improve the accuracy and efficiency of the radiation treatment planning and delivery process by providing accurate visualization of the hardware components and their relative motion. In combination with patient CT data, the treatment planner can virtually simulate patient-specific pre-treatment setups and be able to account for unforeseen collision scenarios for complex conformal beam arrangements.

  2. To improve the learning potential of existing radiation therapy courses by offering radiation therapy technologists 3D content and simulation tools customized for a specific radiation therapy system. The simulation tool can be used for the training of radiation therapy staff, such as dosimetrists and physicists, on various aspects of linac components, motion limitations, and associated accessories.

Project Evolution

The project has undergone much evolution since it originally included the simulator with very limited functionality based on a rough CAD model. Clicking the pictures below, you can access the CAD-based and photograph-based intermediate versions of the simulator. The project is currently versioned as v.2.0.1.

Installation Instructions

The simulator's most up-to-date version is available for registered users only at 3DRTT Simulator.
In order to use the simulator, you need two (2) free software components.
(!) Please install them in this order:

  1. A web browser, Mozilla Firefox or Internet Explorer.
  2. An X3D viewer; we recommend the current version of BitManagement Contact.
    Several previous versions of BS Contact Player are available for download on our website.

The recommended screen resolution is 1280x1024 or higher.
