TOmographic MOdel-BAsed Reconstruction software PAPER (CT Meeting 2020)
ToMoBAR is a Python and Matlab (not currently maintained) library of direct and model-based regularised iterative reconstruction algorithms with a plug-and-play capability. ToMoBAR offers you a selection of various data models and regularisers resulting in complex objectives for tomographic reconstruction. ToMoBAR can handle multi-GPU parallel reconstruction in Python and also device-to-device methods operating on CuPy arrays. |

- DOCUMENTATION is available. Various tutorials are presented and references to API given.
- CuPy-enabled 3D FISTA-OS with regularisation all in-device implementation. It should be 3-5 times faster than the non-CuPy version depending on the GPU device in use and the size of the data.
- Now one can specify the axes labels to describe the input data so it will be automatically passed in the right format to the method. See this Demo.
- Demos changed to adhere the recent changes in TomoPhantom v.3.0.
- A wrapper around ASTRA-toolbox to simplify access to various reconstruction methods available in ASTRA
- Regularised iterative ordered-subsets FISTA reconstruction algorithm with linear and non-linear data fidelities
- Regularised iterative ADMM reconstruction algorithm
- CuPy driven forward/backward projectors to enable faster device-to-device operations and all in GPU memory protoyping of algorithms
- Access to multi-GPU capability through mpi4py library
- Demos to reconstruct synthetic and also real data [4-6]
