This is a fast parallelized tomography projector / backprojector. It originates from solar tomography application but could be use for other applications. It uses the fast Siddon algorithm as its core. The parallelization is done with OpenMP on the C part of the code.

For solar astrophysics, TomograPy allows to perform solar tomographic reconstructions of the corona. It can take SOHO or STEREO data and output a 3-dimensional map of the corona. For now only Extreme-Ultraviolet data is handled but handling of coronographic data is planed along with handling of data from other spacecrafts.

You need numpy, pyfits, fitsarray for siddon to run.

The documentation for TomograPy is embedded into the code as docstrings. To get started, take a look at tomograpy/__init__.py or in IPython, just do :

>>> import tomograpy >>> tomograpy?

For an exemple on how to use TomograPy, see exemple/test_siddon_simu.py

For solar tomography, you need first to process data using http://www.lmsal.com/solarsoft/. Then you can take a look at exemple/siddon_secchi_mask.py or use directly the siddon/srt script.
