This program takes place during the meeting of the American Roentgen Ray Society in Washington, DC, where new developments in X-ray technology are exhibited. After Lynn Poole explains x-rays' discovery by William Roentgen (1895), their definition, and their use, Dr. Russell Morgan interviews three scientists from the conference. Dr. E.S. Gurdjian, a Wayne State University radiologist, describes types of automobile accidents and shows how x-rays can demonstrate the severity of skull fractures at different speeds. Dr. Wallace Tirman, of Caylor Nichol Institute in Bluffton, Indiana, demonstrates a technique for using fine-grain film to make x-rays viewable under a microscope. These microradiographs show thin slices of body tissue for analysis on a diffraction x-ray unit. Dr. Jeffrey P. Moore, of Temple University Hospital in Philadelphia, shows that inserting a needle into a patient's back and injecting an opaque material is a more direct method for x-raying the spinal column to diagnose cartilage problems.
