锥束 CT

锥束 CT(CBCT)在射线源和平板探测器绕物体旋转(通常是一圈圆轨道)时记录二维投影,并由此获得完整的三维体数据。与螺旋扇束 CT 相比,它结构紧凑、成本低,但更容易受到散射、远离中心平面的锥束伪影、截断和运动的影响。

CBCT 是口腔颌面成像、图像引导放疗(直线加速器上的机载成像)、介入 C 形臂系统和四肢扫描仪的标准配置,也是工业 CT 与显微 CT 的常用几何。

FDK 算法仍是主要的重建方法,稀疏或含噪数据则使用迭代和 TV 正则化求解器。近期工作涵盖基于神经衰减场和高斯溅射的稀疏视角 CBCT、面向自适应放疗的 CBCT 图像增强与合成 CT、散射与运动校正,以及针对呼吸运动的 4D-CBCT。TIGRE、RTK 和 ASTRA Toolbox 等开源工具库提供 GPU 锥束投影算子。
