...authors were the 54 foremost cancer combatants, the world's leading specialists in cancer pathology, biology, surgery, X-ray therapy, radium therapy. They wrote in tribute to a great teacher, Professor James Ewing of Cornell Medical School, Manhattan, the man who spent ten years writing Neoplastic Diseases, prime textbook on Cancer. What the 54 authorities wrote comprises a compendium of all current knowledge of Cancer, its causes, treatment, prevention. Because Professor Ewing has always taught that the specialists must depend on the family doctor to discover early signs of cancer, this issue of the Annals of Surgery will...
...Detector. By a new X-ray photographic method called amniography, Dr. Thomas Orville Menees of Blodgett Memorial Hospital, Grand Rapids, Mich., has been able to detect the sex of an unborn child three months before birth. An injection of harmless strontium iodide, opaque to X-rays, makes it possible to identify the structure of the unborn child. Another important use of amniography: to determine cases where a Caesarian section is necessary for safe delivery...
...Technology, a gold medal for a powerful X-ray source developed in his laboratories. The new 650,000-volt tube, the work of Dr. E. C. Lauritsen, is the most powerful ever demonstrated. Dr. William David Coolidge in General Electric Laboratories, Schenectady, has been experimenting for the past year with a 900,000-volt tube not yet perfected for demonstration. Hospitals today use a 200,000-volt tube. Five billion dollars worth of radium (20 Ib.) would be necessary to produce gamma rays equal in power to Dr. Millikan's X-rays. The entire U. S. medical profession today...
Picture Tube. Also revealed at the Radiological Society meeting was the work an X-ray tube can do. Dr. George L. Clark, University of Illinois, told how he took moving pictures of molecules with the help of an X-ray tube. He used a newly developed 50,000-volt tube which makes it possible to take moving X-ray pictures. The tube acts as a powerful microscope. Rays hit the substance which Dr. Clark wished to photograph, were bent back to a fluorescent screen. When the screen was photographed the molecular changes in the substance were apparent...
...basement of the new laboratory, will be rooms for high-pressure experimentation, for x-ray apparatus, and for research in high frequency and vacuum tubes. Beneath this will be a sub-basement where there will be a special x-ray work-room sheathed in lead to prevent the filteration of the rays into photographic appliances or other aparatus that they would harmfully affect. The basment is to be equipped with double walls which will prevent outside disturbances from affecting the extremely delicate measurements essential to research. Rooms will be sound proof and of constant temperature. A huge, 100,000 volt...
