Abstract
The author describes a practical method of X-ray cinematography by which permanent records may be rapidly and inexpensively obtained.A photograph is taken of the screen-image by an ordinary cinematographic camera and by the use of continuous bands of positive film movements may be studied for any length of time. The advantage of this is specially obvious when examining such organs as the heart. These permanent records can be used for the following purposes:-1. Diagnostic.2. To compare with former records, in order to watch effects of treatment, or progress of a pathological condition.3. For teaching purposes.4. For transmission at home or abroad, so that they can be examined by other specialists who may wish to see what the former condition was.The process is simple enough to become routine practice in hospitals and institutions, and to be within the reach of every radiologist.The apparatus occupies only a small space, can be accommodated in any X-ray department, and can be operated by one person.The method is perfectly safe as far as the patient is concerned; that is to say there should be no difficulty in avoiding excessive exposure to radiation.
