would
like to point out the release of a new software package for
electron tomography, called "Ettention". The software was
developed over the last couple of years at the German Research
Center for Artificial Intelligence (DFKI) in Saarbrücken,
Germany, in cooperation with the company EYEN SE, Prague, and
Maastricht University.<o:p></o:p></span></p>

687.0pt 732.8pt"><span
style="font-size:10.0pt;font-family:"Courier
New";mso-fareast-font-family:"Times New Roman"">Ettention
is
released as open source on the platforms Windows and Linux. It
requires a OpenCL compatible high performance computing (HPC)
backend, such as <br>
- NVidia GPU, or<br>
- x86 CPU with OpenCL driver installed, or<br>
- Intel Xeon Phi<br>
<br>
Use Cases so far:<br>
- Ettention provides support for typical iterative
reconstruction methods such as block iterative reconstructions
and SIRT and comes integrated in the eTomo User Interface of
IMOD. It has been used in the NOTOX (FP7-267038) project for
cryo-EM reconstructions of single tilt CTEM data. <o:p></o:p></span></p>
<span style="font-size:10.0pt;font-family:"Courier
New";mso-fareast-font-family:"Times New Roman"">-
Ettention
provides a STEM plugin for the reconstruction of combined tilt-
and focal series data in aberration corrected STEM with limited
depth of field. <o:p></o:p></span><span
style="font-size:10.0pt;font-family:"Courier
New";mso-fareast-font-family:"Times New Roman""><br>
- A laminography plugin has been used in the course of the IMCL
project (AOBJ: 600875) for X-Ray Laminographic reconstructions
using geometric prior knowledge.<o:p></o:p></span>

687.0pt 732.8pt"><span
style="font-size:10.0pt;font-family:"Courier
New";mso-fareast-font-family:"Times New Roman"">The
main
point of Ettention is that, due to a modular design and object
oriented architecture, the system is very extensible and
therefore well suited for algorithmic experiments. The software
automatically takes care of memory mangement on the HPC device
and therefore is suitable for high resolution reconstructions
(2K and more). Ettention is shipped with numerous tutorials and
examples inclusing implementations of the weighted back
projection, weighted SIRT and a tutorial demonstrating the use
of geometric prior knowledge.<o:p></o:p></span></p>
