Hi Martin,<br>
<br>
The displaced detector filter is integrated in the pipeline of all
reconstruction applications in RTK. It will automatically correct
for the shift of your detector if you provide the correct geometry
file. <br>
The geometry information must be obtained from the device you use
for the acquisition, together with the projections. You can simulate
the geometry of a 360° acquisition, with 180 projections (one every
2°) and default Source-Isocenter distance and Source-Detector
distance with the following command : <br>
<br>
rtksimulatedgeometry <span class="re5">-n</span> <span class="nu0">180</span>
<span class="re5">-o</span> geometry.xml<br>
and edit the "geometry.xml" file to understand how it is built. <br>
<br>
If you obtain the geometry information from your device, but fail to
convert it to an xml RTK geometry file, we can provide help to put
you on the right track. <br>
<br>
Regards,<br>
Cyril<br>
