面向髋关节穿刺手术的实用化增强现实导航方法

Practical Augmented Reality Navigation Method for Hip Joint Puncture Surgery

目的旨在利用成熟的技术路线和功能整合,实现面向髋关节穿刺手术的无创伤实用化骨骼增强现实(AR)导航。方法采用基于神经网络的自动分割方法对现有临床CT影像数据进行骨骼图像分割,并进行三维体积重建;利用虚拟现实开发手段,实现手术导航功能。结果实现了面向AR的CT扫描方法及配准装置设计,开发了基于CT影像的实用化骨骼组织三维自动重建功能。成功实现了与真实人体配准的骨组织AR预览。完成了从临床CT影像采集到形成真实人体配准的实时骨骼显示的全过程验证。结论为无创骨骼导航提供了一种新的技术路线和方法,证明了在无创条件下快速实现虚拟骨骼与真实皮肤配准显示的技术可行性。为临床骨科手术提供了新的思路和参考,并可为其他领域的外科手术导航研究提供技术支持和参考。

The work aims to utilize mature technological routes and functional integration to achieve non-invasive practical bone augmented reality(AR)navigation for hip joint puncture surgery.The automatic segmentation method based on neural networks was adopted to segment bone images from existing clinical CT image data and perform 3D volume reconstruction.Virtual reality development methods were used to achieve surgical navigation functions.In this work,a CT scanning method and the registration device design for AR were implemented,and a practical 3D automatic reconstruction function of bone tissue based on CT images was developed.AR preview of bone tissue registration with real human bodies was successfully achieved.The entire process validation from clinical CT image acquisition to real-time bone display for real human registration was completed.This study provides a new technical route and method for non-invasive bone navigation,demonstrating the feasibility of quickly achieving virtual bone and real skin registration display under non-invasive conditions.The results of this study provide new ideas and references for clinical orthopedic surgery,and can provide technical support and reference for surgical navigation research in other fields of surgery.
