BACKGROUND
The clinical feasibility and usability of intraoperative ultrasonography (IOUS) tracked by computed tomography (CT) images have been proposed; however, it requires technically demanding manual registration procedure.
STUDY DESIGN
A prospective study using real-time virtual sonography (RVS) with novel automatic registration system was conducted in four high-volume centers of liver resection from 2015 to 2016. The requiring time for registration of IOUS and CT images and positional error of confluence of middle hepatic venous tributaries (V8-MHV, V5-MHV) were measured in patients undergoing laparotomy.
RESULTS
Automatic registration was successful in 43 of 52 enrolled patients (83%), with error ranges of 11.4 (3.1-69.4) mm for V8-MHV and 16.2 (4.3-66.8) mm for V5-MHV. Time required for total registration process was 36 (27-74) s.
CONCLUSIONS
The RVS with novel automatic registration system can provide quick and easy registration and acceptable accuracy, which can promote the usage of IOUS.
背景
已有人提出通过计算机断层扫描（CT）图像追踪术中超声检查（IOUS）的临床可行性和实用性；然而，这需要技术要求较高的手动配准程序。
研究设计
2015年至2016年，在四个肝脏切除量大的中心进行了一项前瞻性研究，使用具有新型自动配准系统的实时虚拟超声检查（RVS）。对接受剖腹手术的患者测量IOUS和CT图像配准所需时间以及肝中静脉分支汇合处（V8-MHV、V5-MHV）的位置误差。
结果
52例入组患者中有43例（83%）自动配准成功，V8-MHV的误差范围为11.4（3.1-69.4）mm，V5-MHV的误差范围为16.2（4.3-66.8）mm。总配准过程所需时间为36（27-74）秒。
结论
具有新型自动配准系统的RVS可提供快速简便的配准和可接受的准确性，这可促进IOUS的使用。
