Thickness of each esophageal layer: clinical data [39] and data used in our model. Note that the clinical test obtains the thickness of each layer at its non-rest state, with esophageal lumen dilated by the intruded catheter. Computer model adopts the thickness of each layer at its rest state. The thickness of mucosal layer measured based on the ultrasound image is much lower than the thickness at rest, as the intruded catheter will distend the mucosal layer significantly and reduce the layer thickness.
