This is a CBCT projection dataset.
It consists of CBCT projection data of brain, head and neck, lungs, prostate, and pancreas cases.
The projection data were acquired using 3 CBCT systems (XVI Elekta, Varian Truebeam, and IBA Toshiba).
You can find Python scripts to download, read, and visualize the data in the following GitHub repository: https://github.com/MedIP-HKU/CBCT_projection.
The repository also contains a Python script to reconstruct the CBCT images using Reconstruction Toolkit (ITK-RTK).
