【摘要】 目的探讨应用低成本增强现实技术在高血压脑出血神经内镜微创治疗中的可行性和可靠性。方法采集17例高血压脑出血拟行神经内镜微创手术治疗患者头颅CT数据,运用3D-slicer免费软件进行虚拟现实重建并设置标记物后,将重建图片导入智能手机,应用相机功能程序进行头皮与重建图片准确融合,精确描画脑内血肿体表投影,实现增强现实技术,个体化选择手术入路,进而在神经内镜辅助下行脑内血肿清除手术。结果运用低成本增强现实技术17例高血压脑出血患者均可成功完成脑内深部血肿穿刺,并经神经内镜观察证实到达目标部位。结论低成本增强现实技术可以为高血压脑出血的神经内镜微创手术治疗提供准确可靠的定位指导。更多还原

【Abstract】 Objective To investigate the feasibility and reliability of the low-cost augmented reality(AR)in minimally invasive endoscopic treatment of intracranial hemorrhage(ICH).Methods 17 ICH patients treated with minimally invasive endoscopic surgery were recruited.After brain computed tomography(CT)scan,the digital imaging and communications in medicine data(DICOM)were loaded into free software 3 D-slicer.The hematomas and the scalps were reconstructed by the software respectively before the screenshots with markers on the virtual scalp were transmitted to an iPhone5 smart phone.Augmented reality based on an iOS app of camera allowed a projection of the hematoma to be seen on the patients scalp to facilitate selection of the best endoscopy approach.An obturator and transparent sheath were used to establish a working channel,and the surgical evacuation of the hematomas were performed with endoscopy.Results The hematomas of 17 ICH patients were punctured successfully with the low-cost augmented reality technology,and the target locations were verified by the endoscopy.Conclussions The application of low-cost augmented reality in ICH can provide reliable and accurate direction for the minimally invasive endoscopic treatment of intracranial hemorrhage(ICH).更多还原
