带平板探测器的C型臂锥形束计算机断层扫描（CT）代表了介入放射学套件中可用的下一代成像技术，预计将成为许多三维（3D）路线图和导航工具的平台，这些工具将与其集成并行出现。当前和未被认可的功能的组合可能是复杂血管和非血管介入手术安全性和有效性改善的基础。这些改进包括多平面软组织成像、增强的治疗前靶病变路线图和指导以及立即多平面治疗后评估的能力。仅这些关键特征就可以减少碘化造影剂的使用，降低患者和操作员的辐射剂量，增加治疗指数（增加安全受益比）。在常规实践中，使用C形臂锥形束CT获得的成像信息为操作员提供了尚未完全量化的主观置信度。
C-arm cone-beam computed tomography (CT) with a flat-panel detector represents the next generation of imaging technology available in the interventional radiology suite and is predicted to be the platform for many of the three-dimensional (3D) roadmapping and navigational tools that will emerge in parallel with its integration. The combination of current and unappreciated capabilities may be the foundation on which improvements in both safety and effectiveness of complex vascular and nonvascular interventional procedures become possible. These improvements include multiplanar soft tissue imaging, enhanced pretreatment target lesion roadmapping and guidance, and the ability for immediate multiplanar posttreatment assessment. These key features alone may translate to a reduction in the use of iodinated contrast media, a decrease in the radiation dose to the patient and operator, and an increase in the therapeutic index (increase in the safety-vs-benefit ratio). In routine practice, imaging information obtained with C-arm cone-beam CT provides a subjective level of confidence factor to the operator that has not yet been thoroughly quantified.
