How to set tally for the rotated lattice universe?

Hello, thank you for looking my question. I am a beginner in openmc and my question is how to set tally for a large number of universes in the rotated lattice. The model as shown in the figure:


As presented in the brain phantom, I want to count each voxel in the phantom, with the counting grid orthogonal to the phantom, rather than orthogonal to the starting coordinate system.

No matter what your thoughts are, all can reply to me.

Thank you,
