title: Physical and dosimetric aspects of diagnostic geometrical and computer-assisted tomographic procedures.
abstract: Tomographic systems offer potential for visualizing sections of the body that are ambiguously imaged by "flat" detection systems. Effective utilization involves the synergistic combining of various considerations, including appropriate motion, contrast, and extent of the anatomic region of interest; cost-benefit considerations; assurance of correct electromechanical operation; and benefit-risk analysis of patient exposure.
