Figure 2.

Example of small bowel segmentation and quantitative output. A representation of small bowel segmentation, with total bowel cross-sectional area, bowel wall area, and lumen area, expressed as centimeters squared. Projections of segmented bowel rotated about the lumen centerline at 0, 50, 100, and 150 degrees are shown; data from all 360-degree rotational projections are incorporated into bowel measurements. Data can also be exported into tabular format. The conversion from cross sectional area into an ideal equivalent diameter (for bowel dilation and lumen measurements) is the square root of cross-sectional area divided by π.
