计算机断层扫描（CT）系统是利用多角度X光扫描图像，对患者身体内部构造进行三维重建的放射影像学技术。自其发明以来，已经逐渐成为最为重要的一种医学影像学技术。对CT系统的质量控制操作，主要针对其图像质量和放射剂量进行，根据不同的目的和重要性，不同操作的频率也会有所不同。

Computerized tomography (CT) is a radiology imaging technique that takes advantage of multi-angular scanning of patient body and 3-D reconstruction, in order to demonstrate the inner structure of patient body. Ever since its establishment, CT has become the most important tool for medical imaging. Quality control of CT systems is mainly aimed at raising image quality and reducing radiation dose. In the mean time, frequencies of different operations vary according to their purposes and importance.
