Explanation:
I have no idea what this means, but I found it with about ten seconds' Googling.

Phase oversampling, also known as "No Phase Wrap", is a technique to reduce or eliminate the wrap-around artifact. As described in the prior Q&A, phase wrap-around, a form of aliasing, occurs when the anatomic dimensions of an object exceed the defined field-of-view (FOV).
