Photo Gallery: Clinical Bowel Research (1956)
Figure 1. This clinical photograph (above) shows the first use of the flexible colonic echoscope designed to be inserted into the large bowel and to be rotated slowly out with the sound beam pointing at the wall of the colon recording the reflections or echoes from the different anatomical bowel layers. The instrumental assembly shows the manner in which, after manual insertion, the colonic echoscope is slowly wound out on a screw mechanism, which also rotates monitoring equipment attached to the external head of the echoscope so that a recording instrument can examine the internal bowel layers and contiguous organs. With the instrument it was possible for the first time to visualize the layers of the large bowel in order to reveal any abnormalities such as tumors within the wall. Pictured with Dr. Wild is John M. Reid. (St. Barnabas Hospital, MN, 1956)
Figure 2. The record above clearly shows the histological layers of the colon and in the bottom right hand corner some signals from the prostate. The square configuration was due to an unimportant technical problem with the equipment. (St. Barnabas Hospital, 1956) |
