Abstract
In recent years there have been efforts to increase the amount of structural information available in x-ray computed tomography (CT) images. These efforts have proceeded in several directions: increasing the number of resolution elements within a given imaging field; increasing the size of the imaging field for a given resolution element size; and decreasing the imaging field with the number of resolution elements held fixed or increased. This paper will discuss problems common to all of these approaches, with examples referred to two specific CT systems designed for 0.05-mm resolution over a 5-cm field and 2-mm resolution over a 2-meter field. The first problem is that of achieving the desired spatial resolution; the solution is application-dependent and must be discussed individually for each case. The second problem is that of achieving acceptable image noise levels.
