Hey Simon, Thanks for the quick reply.
I did not notice that manual setting was not possible. The set and get functions seemed to return the expected values before requesting the output. The alternative previous version displaced detector filter you suggested runs without any issues.

One of the things that has been developed is a new weighting scheme for offset detectors, see doi.org/10.1118/1.4945418<http://doi.org/10.1118/1.4945418>. In this filter, you cannot specify the minimum and maximum offsets manually: https://github.com/SimonRit/RTK/blob/master/include/rtkDisplacedDetectorForOffsetFieldOfViewImageFilter.hxx#L81-L89 Things should be different with the previous version https://github.com/SimonRit/RTK/blob/master/include/rtkDisplacedDetectorImageFilter.hxx#L130-L149 Can you try this version instead? I have opened an issue to track this problem: https://github.com/SimonRit/RTK/issues/509 Simon On Mon, Sep 19, 2022 at 12:17 PM Nick Staut <nick.st...@smartscientific.nl<mailto:nick.st...@smartscientific.nl>> wrote: Hi everyone, I’ve been trying to use RTK to run a reconstruction during acquisition which runs without issues and returns an acceptable result if I disable the displacedDetectorFilter. However, when I try to enable the displaced detector filter before getting sufficient projections (+ more importantly for the ddf: geometry entries) I get the following error: “ITK ERROR: Cannot account for too large detector displacements, a part of space must be covered by all projections.” I saw that the old rtkinlinefdk implementation (from RTK v1.4 after which it seemed discontinued) manually set the minimum and maximum offsets to the displacedDetectorFilter, however if I do the same now it still fails. To provide a reproducible example I recreated the rtkinlinefdk application following the original format (with small modifications to mimic what I do in my code these modifications are mentioned at the comment at the top of the cxx file). I attached all required files for the example application to the e-mail, it should just compile if you recompile RTK with this unzipped folder in you application directory. Once I understand the issue with the displaced detector filter I could also create a pull request for this rtk application if this is considered useful.
