Some forty-seven years ago, while still an undergraduate, the writer operated a static machine for Dr. H. G. Brainerd of Los Angeles, with which he essayed x-ray diagnosis and conducted experiments with treatment. One day Dr. John B. Murphy of Chicago appeared with a colleague suffering from pain in the kidney, with purulent and bloody urine. Doctor Murphy, suspecting stone, asked if we could make a diagnosis and we made a heroic attempt. An hour's exposure was made, but the x-ray plate was not diagnostic. Another exposure of one and a half hours' duration gave a faint shadow of the spine and abdominal organs, but this was still not sufficient for diagnosis. A few days later the patient's pain had ceased and pus and blood were no longer present in the urine. Within two weeks' time Doctor Murphy pronounced him symptom-free. In other words, it appeared that a therapeutic effect, entirely unexpected, had been achieved. Fortunately, no untoward sequelae developed on the skin or elsewhere, which we now know was due to the absence of quantitative long-wave radiation. This incident awakened a lasting respect for the possibilities of radiation therapy, which leads to the subject at hand; namely, streamlined radiation therapy for present wartime service. Bridging the time since radiation therapy took its first faltering footsteps, let us briefly review its present-day status as a healthy young adult, acclaimed and acknowledged in all intellectual medical centers as a highly specialized and integral part of the practice of medicine. It is futile at present to dream of or await the arrival of multimillion-volt x-ray equipment. This is well on the way and in due time will find its ultimate place in radiation therapy. Meanwhile, let us correlate known facts and factors and adopt a common-sense, middle-ground working technic. Equipment for x-ray therapy may now be accepted as standard, provided it is obtained from a manufacturer of known repute. All such apparatus, irrespective of name, can be integrated and made adaptable for any or all types of therapy which time and experience have proved effective. Many pioneer radiologists have, over a long period of years, placed x-ray therapy upon a solid and sane foundation. The essentials for the average x-ray therapy department are as follows: low-voltage apparatus with a maintained capacity for 100 kv. at the tube's target; high-voltage apparatus with a maintained capacity for 200 kv. at the tube's target; adequate space for placing transformers, control cabinets, connecting lines, treatment tables, and necessary equipment, so as to facilitate therapeutic procedures to the best possible advantage. Particular care must be exercised in providing effective protection from back-scattering, stray radiation, and potential direct or indirect radiation. Cones and filters are necessary adjuvants to x-ray therapy and play a major role in securing accuracy of dosage for the prescribed number of roentgens to be administered.
