Medical procedures are an essential part of healthcare delivery, and the
acquisition of procedural skills is a critical component of medical education.
Unfortunately, procedural skill is not evenly distributed among medical
providers. Skills may vary within departments or institutions, and across
geographic regions, depending on the provider's training and ongoing
experience. We present a mixed reality real-time communication system to
increase access to procedural skill training and to improve remote emergency
assistance. Our system allows a remote expert to guide a local operator through
a medical procedure. RGBD cameras capture a volumetric view of the local scene
including the patient, the operator, and the medical equipment. The volumetric
capture is augmented onto the remote expert's view to allow the expert to
spatially guide the local operator using visual and verbal instructions. We
evaluated our mixed reality communication system in a study in which experts
teach the ultrasound-guided placement of a central venous catheter (CVC) to
students in a simulation setting. The study compares state-of-the-art video
communication against our system. The results indicate that our system enhances
and offers new possibilities for visual communication compared to video
teleconference-based training.

医疗程序是医疗交付的重要组成部分，获取操作技能是医学教育的关键组成部分。我们提出了一个混合现实实时通信系统，以增加对操作技能培训的获取，并改善远程紧急援助。我们的系统允许远程专家通过视觉和口头指导本地操作员进行医疗程序。研究结果表明，我们的系统相对于视频会议培训，可以提供更好的视觉交流和新的可能性。
