Understand metadata to extract subFOV information

Dear community,

I need your help to understand a little bit better the output files I get from our “Ultramicroscope CDC 2x”.
I try to make sense of the metadata found in our acquisition (I converted the info embedded into my image into a json file easier to read than the xml):

z0 is the “big” FOV acquisition
z2 is a zoomed region.

Knowing these metada I would like to know if somebody would be able to tell me where the z2 FOV is within the z0 FOV ?

Our ultimate goal will be to register these images with MRI images, if you have any tips that would be very helpful.

Thank you in advance
