Comparison of image intensifier photofluorography and full-size radiography in abdominal angiography

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.
