Most patients with liver tumors are not candidates for surgical resection. A number of local treatment methods for unresectable liver tumors have recently received considerable interests. The major task of these procedures is accurate needle placement with the aim of complete tumor removal and minimal damage to surrounding normal liver parenchyma. In this article, we review the current status of interventional navigation system (INS) for treatment of unresectable liver tumors in terms of overall workflow, tracking systems, and research development. The conceptual design of INS consists of pre-operative and intra-operative modules. The tracking system falls into three types: optical, electromagnetic, and MR gradient based. The current INS, according to their image modalities, can be classified into four categories: MRI based, CT based, U/S based, and multimodalities based. The article also discusses the future research direction for enhanced performance of INS with real time imaging, high accuracy, high resolution, and friendly user-interface.
大多数肝肿瘤患者不符合手术切除条件。最近，一些不可切除肝肿瘤的局部治疗方法引起了广泛关注。这些方法的主要任务是准确置针，以达到完全切除肿瘤和最小化周围正常肝实质损伤的目的。本文综述了介入导航系统（INS）在不可切除肝肿瘤治疗中的应用现状，包括整体工作流程、跟踪系统和研究进展。INS 的概念设计包括术前和术中模块。跟踪系统分为光学、电磁和基于 MR 梯度三种类型。根据成像方式的不同，目前的 INS 可分为四类：基于 MRI、基于 CT、基于 US 和基于多模态。文章还讨论了提高 INS 实时成像、高精度、高分辨率和友好用户界面性能的未来研究方向。
