The EDI function really just 'shifts the focus' more posteriorly and results in
the anterior layers showing a little less detail and the posterior ones showing
more. Another way to think of it is shifting the sweet spot so that you are
able to image deeper with more resolution. I would be interested in learning
more about caliper placement though too, so if your images show where you put
those, that would be a great thing to share, Jim.
