Abstract
The technical factors in microangiography were studied, and we found that the main limiting factor in resolution was film grain size. Ultrafine grain films exist, but they are very slow, necessitating exposures of several hours at conventional settings. Using a modern beryllium window x-ray unit, equally good images can be made in 2 to 5 minutes by using the minimum tube-to-film distance (32 cm) and the maximum kilovoltage (110 kV).Keywords
