摘要
虚拟肝脏技术借助计算机平台，利用动态三维立体图像取代传统的医学二维图像，能直观、清晰、任意角度地显示肝脏的解剖结构及肝内管道系统的走行、肝脏病灶的位置及其与肝脏血管的空间毗邻关系，提供全方位的肝脏立体信息，并在计算机中构建虚拟的肝脏外科治疗环境。目前虚拟肝脏技术已应用于肝脏外科的诸多领域，如肝切除术、活体肝移植、肝脏体积测量、虚拟肝脏解剖教学、手术仿真训练等方面。本文主要介绍当前虚拟肝脏技术在肝脏外科临床工作中的应用进展。
Three-dimensional modeling of the liver using CT scan or MRI data improves surgical planning. Three- dimensional simulation of hepatectomy facilitates intraoperative identification of the vascular anatomy and control of the hepatic blood flow, and accurately predicts the volume of liver to be resected and surgical margins. Preoperative virtual hepatectomy might be useful not only to facilitate laparoscopic hepatectomy but also to improve therapeutic efficacy. A virtual navigation system enables users to revert to previously recorded digital ima- ging data at any time during radiofrequency ablation procedures. The spatial information gained from three-dimensional imaging facilitates an appropriate needle path to the target and projects the intended ablation area in three dimenisions. The safety and efficacy of radiofrequency ablation assisted by this navigation system may substantially improve as it is used in clinical prac- tice. Augmented reality superimposes the preoperative three- dimensional liver model onto the real intraoperative view of the patient. Augmented reality provides surgeons with a transparent view of the liver and guides surgeons by providing virtual aug- mentation of their real surgical tools. These virtally augmented tools are tracked in real-time during the procedure, thereby optimizing therapy.
