该贡献比较了构成医疗导航系统一部分的光学相干断层扫描 (OCT) 的几何校准的两种方法。为此，分别利用自制的3D参考结构和高精度6自由度（DoF）并联机器人进行了一步标定和多步标定。这些基于 3D 地标的几何校准基于参数化灰盒 OCT 模型的识别。我们在实验结果中表明，两种方法都将系统误差降低了一个数量级以上。
This contribution compares two approaches for the geometric calibration of an optical coherence tomography (OCT) which forms part of a medical navigation system. For this purpose, a one step and a multi step calibration is performed with a self-produced 3D reference structure and a high-accurate 6 degrees of freedom (DoF) parallel robot, respectively. These 3D landmark-based geometric calibrations are based on the identification of a parameterized grey-box OCT model. We show in experimental results that both methods reduce systematic errors by more than one order of magnitude.
