Welcome to toupy documentation

Toupy is a suite of tools for the processing of high-resolution tomography dataset compiled by J. C. da Silva and licensed under the GPLv3 license .

The name toupy stands for Tomographic Utilites for Python and it is a wordplay with the French word toupie for spinning top, the toy designed to spin rapidly on the ground, the motion of which causes it to remain precisely balanced on its tip due to its rotational inertia. Here you can find the wikipedia page in English and in French.

Toupy implements tools for preprocessing the projections before the tomographic reconstruction and the reconstruction itself. The pipeline and algorithms is briefly summarized in this publication 1, but which is also based on previous works 2.
