Description

Tomo3D implements a multithreaded vectorized approach to tomographic reconstruction that takes full advantage of the power in modern multicore computers. Full resolution tomograms are generated at high speed on standard computers with no special system requirements. Tomo3D has the most common reconstruction methods implemented, namely WBP and SIRT. It proves to be competitive with current GPU solutions in terms of processing time, in the order of a few seconds with WBP or minutes with SIRT. Tomo3D reads input tilt-series and writes output tomograms in MRC format. The program is compatible with standard packages, which allows easy integration in the electron tomography workflow.

Version 2.2 contains implementations of the well-known WBP and SIRT methods, and WBP using a SIRT-like filter (also known as 'Fake SIRT') as well as CTF deconvolution using D. Tegunov's filter.

A detailed description of the procedure implemented in the package can be found in the following articles:
