锥形束计算机断层扫描（CT）有可能减少CT扫描仪的尺寸和成本。由于这项新兴技术产生的图像具有各向同性的亚毫米空间分辨率，因此非常适合专用的牙颌面CT扫描。当与特定应用软件工具相结合时，锥形束计算机断层扫描可以为牙颌面医生提供完整的解决方案，用于执行特定的诊断和手术任务，例如牙科种植计划。在本文中，我们提供了锥形束扫描技术的简要概述，并将其与传统CT扫描仪中使用的扇形束扫描进行比较。我们介绍'DentoCAT'，一个相对较小的，低成本的锥束CT扫描仪专用于牙颌面成像开发的Xoran技术。我们展示了DentoCAT扫描仪生成的图像，并在空间分辨率和有效辐射剂量方面对其性能进行了评估。最后，我们通过展示我们迄今为止使用DentoCAT扫描仪结合种植规划软件工具获得的结果来说明扫描仪的临床实用性。
Cone beam computed tomography (CT) has the potential to reduce the size and cost of CT scanners. Because this emerging technology produces images with isotropic submillimeter spatial resolution, it is ideally suited for dedicated dentomaxillofacial CT scanning. When combined with application-specific software tools, cone beam computed tomography can provide dentomaxillofacial practitioners with a complete solution for performing specific diagnostic and surgical tasks, such as dental implant planning. In this paper, we provide a brief overview of cone beam scanning technology and compare it with the fan beam scanning used in conventional CT scanners. We introduce 'DentoCAT', a relatively small, low-cost cone beam CT scanner dedicated for dentomaxillofacial imaging developed at Xoran Technologies. We present images generated by the DentoCAT scanner and provide an assessment of its performance in terms of spatial resolution and effective radiation dose. Finally, we illustrate the clinical utility of the scanner by presenting the results we have obtained to date using the DentoCAT scanner in conjunction with an implant planning software tool.
