Motility patterns of ex vivo intestine segments depend on perfusion mode

Figure 4 Different motility patterns as presented in heatmaps after processing the raw video data. A correlation between gut diameter and colour used can be seen in the legend on the right hand side. Graphic drawings on top of the individual heatmap do represent the intestinal movements seen in the heatmap images. The distension of the wavefront is marked in image (B), (D) and (F). Measuring point 32 represents the oral side, measuring point 0 the anal side of the intestinal segment. Different types of contractions could be observed A: MP1 anal direction; B: MP1 anal direction with a broadening of the wavefront; C: MP2 oral direction; D: MP2 oral direction with a broadening of the wavefront; E: MP3 anal and oral direction; F: MP3 anal and oral direction with a broadening of the wavefront; G: Irregular pattern. MP: Motility pattern.
