Summary

This notebook shows how to simulate a CT scan acquisition with gVXR and reconstruct the corresponding CT volume with CIL.

Aims of this session

1. Simulate a low-dose CBCT scan acquisition using gVXR, either
   • adding quite a bit of noise to mimic a low exposure, and/or
   • reducing the number of projections taken around the patient.
2. Reconstruct the CT volume using the Core Imaging Library (CIL) with
   • the filtered-back projection (FBP), and
   • a gradient descent (iterative).
