BACKGROUND AND PURPOSE The GestSure system is an Food and Drugs Administration (FDA)-registered depth-sensing infrared device initially developed for touchless image navigation during open surgery. The goal of this study was to explore the feasibility of this technology with medical students, residents, fellows and staff neurointerventionalists, using cases of intracranial aneurysm coiling. MATERIAL AND METHODS This was a prospective cohort study of operative performance using standard keyboard and mouse against a gestural interface. A total of four medical students, six residents, six fellows and five staff neurointerventionalists were involved in the training and subsequent testing. Training involved description and demonstration of a set of gestures optimized for 3D software functions. Cases were selected from the set of patients who underwent endovascular aneurysm coiling at the Toronto Western Hospital. RESULTS AND CONCLUSION For the overall group 15/21 (71.4%) individuals learned the left anterior oblique 30 degrees (LAO30) task within 20 cases, 17/21 (80.9%) learned the aneurysm neck task within 20 cases, 16/21 (76.2%) learned the parent vessel task and 14/21 (66%) learned the neck and parent vessel (anatomical) tasks. Staff were more consistent (i.e. smallest standard deviation) amongst the groups compared to medical students and residents; however, it was noted that a significant learning effect was observed in participants across every level of medical and angiographic expertise. Touchless angiography suite control with a gestural interface is feasible for the manipulation of angiographic images for neuroendovascular procedures. Learning to use the system was rapid across any level of medical training but greatest for staff neurointerventionalists.

用于神经血管内手术的非接触式血管造影套件计算机控制器的评估。

背景和目的 GestSure 系统是食品和药物管理局 (FDA) 注册的深度感应红外设备，最初开发用于开放手术期间的非接触式图像导航。本研究的目的是使用颅内动脉瘤卷曲病例，与医学生、住院医师、研究员和神经介入医师一起探讨这项技术的可行性。材料和方法 这是一项针对手势界面使用标准键盘和鼠标的手术性能的前瞻性队列研究。共有四名医学生、六名住院医师、六名研究员和五名神经介入医师参与了培训和后续测试。培训涉及一组针对 3D 软件功能优化的手势的描述和演示。病例选自在多伦多西部医院接受血管内动脉瘤栓塞术的患者。结果与结论 全组15/21（71.4%）人在20例内学会了左前斜30度（LAO30）任务，17/21（80.9%）在20例内学会了动脉瘤颈任务，16/21（ 76.2%) 学习了母血管任务，14/21 (66%) 学习了颈部和母血管（解剖）任务。与医学生和住院医师相比，各组的工作人员更加一致（即最小标准差）；然而，值得注意的是，在医疗和血管造影专业知识的各个级别的参与者中都观察到了显着的学习效果。具有手势界面的非接触式血管造影套件控制对于神经血管内手术的血管造影图像的操作是可行的。在任何级别的医学培训中，学习使用该系统的速度都很快，但对于神经介入医生来说，学习效果最好。
