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.

摘要

断层扫描系统能够对“平面”检测系统成像模糊的身体部位进行可视化。有效利用该系统需要综合考虑多个因素，包括适当的运动、对比度、感兴趣解剖区域的范围；成本效益考量；确保机电操作正确；以及对患者辐射的利弊分析。
