...streamlined dentists' office just off Manhattan's Fifth Avenue a decided improvement in X-ray could be seen last week. It consisted of some amazing X-ray transparencies. Each one appeared fuzzy to the naked eye, like seeing double. But through polaroid eyeglasses each transparency was a clear, three-dimensional, stereoscopic view into a body. A pencil moving over a film of the chest seemed to move among the ribs, poke the heart. Three dentist brothers, Edward, Milton, Harold Klein, perfected the method...
...trouble with most previous stereoscopic X-rays, the Kleins explain,* was that the two exposures were made the same way stereoscopic photographs are made: i.e., by moving the X-ray tube two and a half inches (average distance between eye pupils) between shots. But an X-ray tube does not correspond to an eye, as a camera does. It corresponds to a light source which shoots rays through the subject to make shadows on the film beyond. Moving the tube two and a half inches produces too much disparity in the resulting films. Viewed through a stereoscope, such pictures will...
...general location of the bullet (see cut), but no operation was performed. A more accurate guess (through deduction) by Anatomist Feneuil Dunkin Weisse was also disregarded, but later proved by autopsy. A wag cracked: "When ignorance is Bliss, 'tis folly to be Weisse." Two Points. Even though X-ray has long been in use, research on finding foreign bodies still goes on in the attempt to bridge a surgeon's difficulty in not being able to see what he is after. Even with the best modern methods he sometimes scores a miss...
...surgeon cuts along the line between the two marks, Dr. Cole says he cannot miss. Special equipment includes X-ray calipers to check correct positioning of the marks, and duplicate surgical calipers which, when properly set, point directly to the foreign body. Both kinds of calipers are placed with one arm above and the other below the injury; when the operation is done, the surgical calipers duplicate the position of the X-ray calipers...
...Planes. The Army's standard equipment is the mobile X-ray unit, of which the Medical Corps has more than 3,000 (cost: $2,380 each). The outfit, consisting of an X-ray machine, a generator, a tent darkroom and a table for patients, is carried in three Army trunks and takes six minutes to assemble in the field. As no calipers are used, an injured man need not be moved while he is on the table. In most cases the X-ray man merely spots the foreign body by fluoroscopy and gives the surgeon a report...
