There is no documentation of the 3-D dimensions of normal rectum. We present a method for the architectural and volumetric analysis of the rectum which makes use of a computerized 3-D reconstruction and CT scans of cross-sections of the rectum. The technique is simple, fast, yet potentially reliable. An attempt has been made to calculate the volume, area and average diameter of non-distended rectums (normal). Once we can standardize the technique, then we can study dimensions of the rectum in adult males and females. This thesis constitutes a unified presentation of the essential aspects of the method used in this study.

We plan to study the dimensions of distended rectums (normal) measured in single column Barium Enema X-rays in two views. Once the technique is standardized, it can be applied to study the dimensions of diseased rectums.
