This document outlines the imaging strategy for Barrett's sample, focusing on region A. The initial step involves capturing a 340 x 340 µm image of Barrett's Area A. Following this, a detailed zoom into a 42 x 42 µm section will provide insights into Barrett's features, which may appear as small spheres in topographic images. Various box sizes corresponding to 42 x 42 µm and 85 x 85 µm are depicted, with locations determined via SNOM images. Future imaging may also extend to the stroma and other Barrett's areas presented in previous slides.

On this figure are marked various regions of interest, which are given letters to distinguish them. It is planned to start with region A.
The general plan for Barretts sample is to: • First image a 340 x 340 um “Barrett’s” area, shown here are area A • Next is to zoom down (to 42x42 um?) within this area to look are the Barrett’s. This should/might manifest itself as small spheres in our topographic images. Shown on slide 5 are several sizes of boxes representing the size of 42x42 um images and 85x85 um. The exact location of these boxes should be determined by examination of our SNOM images (the exception is the box around the stroma). • After we are fairly sure we have good images of Barrett’s, we might obtain an image of the stroma. An area thought to be stroma is shown in slide 5. • You will note that there are other area of Barretts shown in slide 2, which we migth explore.
