Cone-beam computed tomography (CBCT) is a relatively new technique. It generates a 3D image by emitting a pulsed cone-shaped X-ray beam. CBCT has become a very useful and widely used technique for dentomaxillofacial imaging over the last decade. It provides clear, high resolution multiplanar reconstruction images. Previously, the images could only be generated while the patient was sitting with his/her head fixed in position. With the presented new generation CBCT (NewTom 5G, QR, Verona, Italy), a more free positioning of the patient, either lying or sitting, is possible. In this way, skeletal imaging of various body parts becomes possible. In this article we present three clinical cases of CBCT imaging of the wrist, describe the background of the technique, and discuss the advantages and disadvantages of CBCT imaging.
锥形束计算机断层扫描（CBCT）是一种相对较新的技术。它通过发射脉冲锥形 X 射线束生成 3D 图像。在过去十年中，CBCT 已成为一种非常有用且广泛应用于口腔颌面成像的技术。它提供了清晰的、高分辨率的多平面重建图像。以前，只有当患者头部固定坐着时才能生成图像。使用新一代的 CBCT（NewTom 5G、QR、Verona、意大利），患者可以更自由地选择躺着或坐着的姿势。通过这种方式，可以对身体的各个部位进行骨骼成像。在本文中，我们介绍了三个手腕 CBCT 成像的临床案例，描述了该技术的背景，并讨论了 CBCT 成像的优缺点。
