Computerized tomography has become an essential element in the staging of tumors and in the localization of the tumor and neighboring normal tissues for treatment planning. It offers the potential for more accurate delivery of higher doses with improved therapeutic ratio, for the identification of and correction for tissue inhomogeneities, and for three-dimensional treatment planning. For treatment planning purposes only minor changes are required in the current generation of scanners. Possibilities for the future include dynamic radiation treatment, combined CT scanners, simulators, and treatment planning computers, and a potential for significant cost saving through improvements in the results of cancer therapy.
计算机断层扫描已成为肿瘤分期以及为治疗计划确定肿瘤和邻近正常组织位置的重要手段。它有可能更精确地给予更高剂量，提高治疗比，识别并校正组织不均匀性，以及进行三维治疗计划。就治疗计划而言，当前一代扫描仪只需做些小改动。未来的可能性包括动态放射治疗、联合CT扫描仪、模拟定位器和治疗计划计算机，以及通过改善癌症治疗效果实现显著成本节约的潜力。
