摘要
目的:开发软组织形变的实时跟踪系统,可有效提高胸腹部手术的精度,降低手术损伤率。方法:利用术前CT/MRI图像、术中超声成像与电磁定位系统相结合的方法,实时跟踪软组织形变。结果:通过结合术前图像高分辨率和术中超声实时性的优点,解决了软组织导航技术的关键问题,并通过试验验证了软组织形变跟踪技术在临床应用的可行性。结论:将术前、术中影像及电磁定位系统相结合,不仅为软组织形变实时跟踪提供了一个可行的手段,而且对胸腹部手术的术中导航技术的实施和应用奠定了基础。
Objective： The real-time and accurate tracking of soft tissue deformation can improve the accuracy of chest/abdominal operation and reduce damage. Methods： The preoperative CT/MRI images, intra-operative ultrasound image and electromagnetic tracking system were combined for real-time tracking of soft tissue deformation. Results： The system integrates advantage of high resolution of pre-operative images and real-time feature of ultrasound imaging for tracking the soft tissue deformation. Volunteer study has indicated feasibility of the system for clinical application. Conclusion： The combination of preoperative and intra-operative image and electromagnetic tracking system provides a possible means for the property study of soft tissue and lays the foundation for the implement and application of the chest/abdominal navigation.
