A water-cooled X-ray tube

A new water-cooled, high voltage, X-Ray tube, developed by Dr. W. D. Coolidge of the General Electric research laboratory, has received a hearty medical endorsement, following a thorough trial in cancer treatment by Dr. James T. Case, a prominent X-Ray specialist of Battle Creek, Michigan. Doctor Case installed one of these tubes in the radiotherapy department of the Battle Creek Sanitarium in the summer of 1923, where a large series of animal experiments was undertaken. Since the first of August, 1923, all the clinical material requiring roentgenotherapy at that institution was handled with the new tube.
