CIL is an open-source mainly Python framework for tomographic imaging for cone and parallel beam geometries. It comes with tools for loading, preprocessing, reconstructing and visualising tomographic data.
CIL provides optimised standard methods such as Filtered Back Projection and FDK and an extensive modular optimisation framework for prototyping reconstruction methods including sparsity and total variation regularisation, useful when conventional filtered backprojection reconstruction do not lead to satisfactory results, as in highly noisy, incomplete, non-standard or multichannel data arising for example in dynamic, spectral and in situ tomography.
CIL is open-source software released under the Apache v2.0 licence.
We have a repository with a large collection of Jupyter Notebooks which cover a wide range of topics, from basic usage to advanced reconstructions with iterative methods.
Some examples without any local installation are provided in Binder. Please click the button below to try them immediately in your browser.
CIL has a live documentation which gets updated regularly and built nightly. We suggest to download and read the open access articles below, which provide very detailed information about CIL structure and usage.
