gVirtualXray user training day at IBSim-4i 2022

• Session 1
  • Notebook 0 -- Warming up
    • Log in;
    • Copy the training data;
    • Install the Python packages needed for this course;
    • Check that gVirtualXray is working well;
    • Verify which version of gVirtualXray is installed (software and hardware);
    • How to get help (during and after the training).
  • Notebook 1 -- Introduction to X-ray attenuation and its implementation in gVirtualXray
    • Explain what gVXR is and why it has been developed;
    • Introduce projection X-ray imaging and how X-rays are produced;
    • Understand how X-rays interact with matter;
    • Become familiar with the Beer-Lambert law to compute the attenuation of X-rays by matter;
    • Describe how the Beer-Lambert law is implemented in gVirtualXray;
    • Compare images simulated using gVirtualXray with ground truth images.
• Session 2
  • Notebook 2 -- First X-ray radiograph simulations
    • Create our first X-ray simulation, step-by-step;
    • Save our X-ray image in a file format that preserves the original dynamic range;
    • Visualise the results with 3 different look-up tables;
    • Visualise the 3D environment.
