The serial large-field angiography is undoubtedly useful in the roentgenographic evaluation on the vascular diseases involving systemically throughout the body or lower extremity. The large-field angiography has been routinely performed in the arterial or venous ailments of the extremities in our Department of Radiology since 1965,using a long cassette (90×25cm) holding a differential intensifying screen for the whole-limb angiography. A new automatic roll-film changer for the large-field angiography was constructed by Dr.Suzuki (Director of our Department) in 1977. The changer is equipped with a combination of intensifying screens (90×25cm) for the whole-limb angiography and a 90×25cm stationary grid. The program of film changing can be set at 1 exposure per 1,2,3,4 or 5 second period on the program selector, and a total of 20 serial angiograms can be obtained. In addition to results on basic experiment, some of clinical experience on the changer is presented.
