High-resolution images from VLE. (A) A transverse cross-sectional image showing all architectural layers of the squamous mucosa, including the epithelium (e), lamina propria (lp), muscularis mucosa (mm), submucosa (sm), and muscularis propria (mp); because of the large change in esophageal circumference during imaging (56 mm) and after resection (~22 mm), the cross-sectional image is displayed over a proportionately larger width. (B) Representative histology from the same swine (H&E, orig. mag. x2). Reprinted with permission from Vakoc BJ, et al. [70].
