Surgical process analysis for supporting complex information- guided surgery environment

在这个项目中，我们的目标是为外科工作流程创建一个新的分析系统，以实现高质量的手术。特别地，我们利用手术导航系统的信息和手术室的视频图像，开发了imri引导的胶质瘤手术和腹腔镜胆囊切除术的工作流程分析系统。该系统仅使用手术导航信息，就能对手术流程进行估计和量化。通过对手术室的视频分析，显示了对医务人员三维轨迹的可视化分析能力和工作流程估计能力。

On this project we aimed to create a novel analysis system for a surgical workflow to achieve high-quality surgery. Especially, we developed workflow analysis system for iMRI-guided glioma surgery and laparoscopic cholecystectomy using the information from surgical navigation system and video images in operation rooms (OR). Our system showed great ability for workflow estimation and quantification of the characteristics of surgeons' procedures only using surgical navigation information. The results o video analysis of OR show the ability of visualization and analysis of 3 dimensional trajectory of medical staff, and the ability of workflow estimation.
