基于术中超声的导航系统已被引入用于不同的外科手术和干预。超声探头校准的准确度是对导航系统整体准确度的主要贡献。介绍了基于体模的各种标定方法。校准过程的挑战是准确地识别超声图像中的体模结构，并可能自动识别。在大多数情况下，2D超声探头已经过校准。3D探头的优势在于可开箱即用地采集3D超声体积，从而实现仅基于一次图像采集的快速校准方法。本文介绍了一种新的廉价、易于制造的平面体模和三维超声探头的自动校准算法。
Navigation systems based on intra-operative ultrasound have been introduced for different surgical procedures and interventions. The accuracy of the ultrasound probe calibration is a main contribution to the overall accuracy of the navigation system. Different calibration methods based on phantoms have been introduced. The challenge of the calibration procedure is to identify the phantom structures accurately and possibly automatically in ultrasound images. In the majority of cases 2D ultrasound probes have been calibrated. The advantage of 3D probes is the acquisition of 3D ultrasound volumes out of the box enabling fast calibration approaches based on only one image acquisition. We introduce a new inexpensive and easily to manufacture planes phantom and automatic calibration algorithm for 3D ultrasound probes.
