摘要
神经导航系统设备昂贵、操作复杂且普及率低,仅存于部分大型医疗机构。为了满足其他中小型医疗机构对于神经外科手术导航系统的需求,本文阐述了一种基于增强现实(AR)理论开发的头颅体表定位系统。该系统借鉴AR技术将虚拟世界影像与现实世界影像相融合的思想,将患者头部计算机断层扫描成像(CT)或磁共振成像(MRI)与现实中患者头颅进行投影融合,实现头颅体表定位。文章重点讨论医学图像可视化中医学数字成像和通信(DICOM)国际标准、三维重建、AR图像图层融合等关键点。本研究测试表明,该系统适用于多款手机,能实现二维图像展示、三维重建渲染以及临床头颅体表定位应用,对于辅助神经外科手术头颅体表定位具有一定意义。
Neurosurgery navigation system,which is expensive and complicated to operate,has a low penetration rate,and is only found in some large medical institutions.In order to meet the needs of other small and medium-sized medical institutions for neurosurgical navigation systems,the scalp localization system of neurosurgery based on augmented reality(AR)theory was developed.AR technology is used to fuse virtual world images with real images.The system integrates computed tomography(CT)or magnetic resonance imaging(MRI)with the patient's head in real life to achieve the scalp positioning.This article focuses on the key points of Digital Imaging and Communications in Medicine(DICOM)standard,three-dimensional(3D)reconstruction,and AR image layer fusion in medical image visualization.This research shows that the system is suitable for a variety of mobile phones,can achieve two-dimensional(2D)image display,3D rendering and clinical scalp positioning application,which has a certain significance for the auxiliary neurosurgical head surface positioning.
