For a number of years multi-format or multi-image cameras have been used in radiology departments to record images for ultrasound, nuclear medicine and computerized tomography. The authors have described in previous papers the development of a total low dose fluoroscopy system, using a Siemens Videomed H 1023 line 25 MHz television system, a V.A.S. video disc recorder for pulsed fluoroscopy, and a modified Matrix Videoimager to record the spot film images. This approach has provided images of high quality with dose and cost reductions of the order of 90% for the total examination. The particular problems involved with the modification of a multi-image camera for fluoroscopic or radiographic procedures, can be minimised by appropriate choice of monitor phosphor and correct control of the exposure sequence.
