本文提出了一种非刚性的二维/三维（2-D/3-D）配准框架及其体模验证对象特定的支气管镜模拟。该方法利用了最近开发的五自由度小型化导管尖端电磁跟踪器，使得可以准确地确定支气管镜的位置和方向。这允许有效地恢复未知的相机旋转和气道变形，这是由主动形状模型（ASM）建模。ASM捕获呼吸期间气管支气管树的内在变异性，并且它特定于它所代表的运动类别。该方法减少了控制变形的参数的数量，从而大大简化了优化过程。随后，执行基于pq的配准以恢复相机姿态和ASM的参数。算法的详细评估是在可变形气道模型上进行的，地面实况数据由额外的六自由度电磁（EM）跟踪器提供，以监测模拟呼吸运动的水平
This paper presents a nonrigid two-dimensional/three-dimensional (2-D/3-D) registration framework and its phantom validation for subject-specific bronchoscope simulation. The method exploits the recent development of five degrees-of-freedom miniaturized catheter tip electromagnetic trackers such that the position and orientation of the bronchoscope can be accurately determined. This allows the effective recovery of unknown camera rotation and airway deformation, which is modelled by an active shape model (ASM). ASM captures the intrinsic variability of the tracheo-bronchial tree during breathing and it is specific to the class of motion it represents. The method reduces the number of parameters that control the deformation, and thus greatly simplifies the optimisation procedure. Subsequently, pq-based registration is performed to recover both the camera pose and parameters of the ASM. Detailed assessment of the algorithm is performed on a deformable airway phantom, with the ground truth data being provided by an additional six degrees-of-freedom electromagnetic (EM) tracker to monitor the level of simulated respiratory motion
