I try to reproduce CT reconstruction in the paper Laminography in the Lab: Imaging planar objects using a conventional x-ray CT scanner download link
In this study, the object is tilted and the object stage is rotate along the tilted axis.
Based the TIGRE demo example, DEMO 18: Arbitrary axis of rotation, I tried to reconstruct the LEGO volume.
According to the demo example, it says:
In TIGRE this has been implemented by defining the rotation with 3 angles, specifically the ZYZ configuration of Euler angles.
So, I first converted the rotation angles to Euler angles.
the reconstruction result seems right!
This result confused me, since this is not ZYZ.
Hopefully, there is someone can help me to figure this out. Thanks!
In all references listed in Further Reading and code, talk very little about the spherical trajectory of both detector and X-ray source. Is it possible to elaborate this part in TIGRE?
Thanks!!!
Both test code and the projection data are available here

Based the TIGRE demo example, DEMO 18: Arbitrary axis of rotation, I tried to reconstruct the LEGO volume.
According to the demo example, it says:
So, I first converted the rotation angles to Euler angles.
But the reconstruction result is totally wrong.
However, when I set the angles this way:
the reconstruction result seems right!
