Ettention is a software package for tomographic reconstruction in electron tomography. It implements the algorithms simultaneous algebraic reconstruction technique (SART), simultaneous iterative reconstruction technique (SIRT) and a generic, block-iterative reconstruction algorithm. Ettention is written in C++ and internally uses OpenCL to run on a large number of high-performance computing.

The software supports single tilt, parallel projections for the use with conventional transmission electron microscopy data. Support for a combined tilt- and focal series for use in high-angle annular dark field scanning transmission electron microscopy (HA-ADF STEM) is provided via plugin. Also via plugin comes support for X-Ray laminography reconstruction.
Precompiled binaries are provided in the download section. The software can be operated from the command line or via an integration in the eTomo graphical user interface of the IMOD software package.
