OpenMBIR-ParBeam

BASELINE MBIR RECONSTRUCTION SOFTWARE FOR 2D and 3D PARALLEL-BEAM CT

This is a reference implementation of MBIR, but it is not parallel or optimized for speed. A much faster version of this parallel beam MBIR algorithm is available at: https://github.com/HPImaging/sv-mbirct

For other OpenMBIR packages see: https://github.com/cabouman/OpenMBIR-Index

1) Install the required software

2) Compile the code. From the main directory run cd src && make && cd ~-. The executables will be stored in the bin folder.

3) Run the demos

• In the demos folder there are fast and slow 2D and 3D demos
• To run a demo execute the respective runDemo.sh script.

• To display the result run the displayImage.sh script.

  The displayImage.sh script makes use of the python IO Utilities in IO-Utils. You can use these utilities to read the images into a python numpy array.
