[Three-dimensional longitudinal dissection view of hollow viscus].
To visualize the pathologies of hollow viscus and their extension three-dimensionally, volume data of the larynx, trachea, stomach, rectum, and urinary bladder were obtained using helical CT with moderately thin slices. Longitudinal cut sections were made as in a simulated surgical cut, and the interior morphology was displayed along with the pathology. A cylindrical projection profile was made by making a longitudinal incision on one wall and pulling apart the flaps to reveal the interior, providing better visual perception. The detailed outline from the 3D profile and the cylindrical projection views constituted an added advantage over the existing procedures.
