The State-of-the-Art in Medical Computed Tomography

A new development in computed tomography display systems permits dynamic review of image data along arbitrary planes. This has been shown to be a major step towards the goal of true three-dimensional presentation of clinical information. With the advent of three-dimensional viewing capability, it is necessary to expand the concept of spatial resolution to include the slice thickness parameter. The spatial resolution specification will now have three orthogonal components, and the goal will be to make the longitudinal component more nearly equal to the components in the scan plane.
