Conventional cineradiography, by photography of the fluorescent screen, suffers from the disadvantages of causing high radiation dosage to the patient and heavy loading of the X-ray apparatus. The advent of the image amplifier has provided a means of reducing these hazards. As yet the field of view of the available amplifiers is restricted to a 5 in. circle, but nevertheless cine-radiography of this area may be useful, particularly in paediatrics. The following account concerns practical details of a simple but effective technique in which emphasis has been placed on the use of commercially available apparatus. The only other item required is a simple form of mounting that can be assembled in the X-ray department or by the hospital carpenter. General Radiological electronic generator with standard Pantoscope table: Mullard MRA overcouch tube. The table has been fitted by the makers with a plug socket so that external contacts may initiate exposures. The lack of switching inertia and the accuracy of short exposures permitted by the electronic control on this set allows each cineframe to be exposed as an individual radiograph even when filming at 64 pictures per second. With the Bucky diaphragm locked at the foot of the table and the screen carriage at the head there is sufficient room to place the cinematographic apparatus below the middle portion of the table, leaving the upper surface very conveniently free for such procedures as angiocardiography.
