In this example, the slices of the two volumes are reconstructed in the axial plane of the patient; the row direction is aligned in the positive x-direction of the patient (right-left) and the column direction is aligned in the positive y-direction of the patient (anterior-posterior).

The full field of view reconstruction in encoded with the Instance UID "Z1" and consists of a 512 cube volume of 0.2 mm of voxel size. The sub-region reconstruction in encoded with the Instance UID "Z2" and consists of a 256 cube volume of the voxel size of 0.1 mm.

Both volumes share the same Frame of Reference UID.
