Abstract
From the computer simulation study of blood vessel imaging in cerebral angiography it is found that, with proper choice of the focal‐spot size and magnification ratio, radiographic magnification in conjunction with fast screens can give blood vessel images “equivalent” to or better than those from slower screens without magnification. However, this result is highly dependent on blood vessel diameter. If a sufficiently small focal spot is not available so that the proper choice of focal‐spot size and magnification cannot be made, then the vessel image from slower screens without magnification can be better than that from fast screens with magnification.
