Physical properties of photofluorography using an image intensifier tube with an input field of 30, 23 or 17 cm and 100 mm film were analysed and compared with full-size film in abdominal angiography. Factors influencing the image quality are discussed. The quality of the 100 mm films comes rather close to that of full-size films. When 17 and 23 cm input fields are sufficient, image intensifier photofluorography may replace full-size radiography. The 30 cm input field may be used in examinations of large vessels, to shorten exposure times in obese patients and in some special projections.
