The authors report the results obtained with a new 105 mm ampliphotographic camera for filming at high speeds (camera GV 105 of the General Radiological Company). Thanks to a rate of 8 films per second, this camera seems particularly interesting for the study of sphincters and fleeting phenomena. However, the quality of the images, comparable with those of standard films, the rapidity of the examinations, the easy reading of the films, the important reduction in the dose of X Rays delivered and the economy of film, render advisable the use of this technique in general radiology. Unfortunately, there is not at present a simple, rapid formula for presentation of the films obtained. Progress will also have to be made in order to facilitate loading of the camera. Rapid resolution of these problems will permit this technique to be more widely used.
