手术计划软件是治疗肿瘤疾病的关键组成部分。然而，基于桌面的系统仅提供有限的可视化和交互机会。此外，手术团队成员之间的协作计划仅在有限程度上是可能的。在这项工作中，一个协作的虚拟现实（VR）环境，以协助肝脏外科医生在肿瘤手术规划。我们的目标是改善外科医生在远程或协同定位环境中的虚拟切除计划。该系统允许外科医生在患者特定的器官3D表面和2D图像切片上定义和调整虚拟切除。两种模式上的变化是同步的，这将使外科医生能够快速地调整和优化切除表面。此外，还提供了实时风险地图可视化，显示肿瘤周围的安全裕度。由肝脏外科医生进行的评估提供了有关潜在受益的信息，例如可视化复杂病例的可能性和评估安全关键区域，适用性和进一步改进的局限性。(c)2021爱思唯尔有限公司保留所有权利。
Surgical planning software is a key component in the treatment of tumor diseases. However, desktop based systems provide only limited visualization and interaction opportunities. Moreover, collaborative planning among members of a surgical team is only possible to a limited extent. In this work, a collaborative virtual reality (VR) environment to assist liver surgeons in tumor surgery planning is presented. Our aim is to improve virtual resection planning between surgeons in a remote or co-located environment. The system allows surgeons to define and adjust virtual resections on patient-specific organ 3D surfaces and 2D image slices. Changes on both modalities are synchronized, which will enable surgeons to iterate and refine the resection surfaces quickly. In addition, a real-time risk map visualization is presented that displays safety margins around tumors. An evaluation performed by liver surgeons provides information on potential benefits, such as the possibility to visualize complex cases and assessing the safety-critical areas, applicability, and limitations for further improvement.
