According to the documentation, the world geometry origin should be in the bottom-left-back corner. This is true for the sagittal and coronal (aka. frontal) window of the MITK display, but in the axial window the origin happens to be in the top-left-front corner, actually.
There is also a half voxel shift in each render window, for which I sent patches in #17812. With those fixes the corner points are the same in the three renderers, just the origin is different in the axial one.
I am wondering if you consider this as a bug or if there is intention to change this for consistency, or if you would accept merge request for this.
#17812 is marked as high priority, and so should be this one, I think, so that all these geometry issues could be fixed in one go. If someone relies on the current behaviour, they would need to update their code only once.
