Why do you even need to do this? If I understand you, the difference between these images arises only from the different  location and geometry of the fields of view chosen at scan time. The object is the same for both and has not moved in any way. Assuming you know how the field of view changed from one scan to the next, can't you then just infer the transformation from that?

Failing that, we need to see some code in order to ascertain what went wrong.
