The physician-to-population ratio is beginning to plateau, and is expected to decline right as the U.S. elderly (and more medically needy) population is on the rise. Thus, the physician workforce may not be able fulfill the U.S. population's demand. In fact, in 2020, the United States may face shortages of 45,400 primary care physicians and 46,100 medical specialists—a total of 91,500 too few doctors. Other projections estimate that the supply of US physicians may decrease even lower, with a shortfall as high as over 200,000 by 2020. Furthermore, the amount of quality time medical students have to learn procedures has drawn concern from researchers. ArchieMD has been developing a medical simulation augmented reality system to combine multimedia technologies with manikins to enable internal anatomy overlays on medical trainers. ArchieMD developed the technology based on a human manikin task trainer combined with 2D and 3D anatomic visual models presented on a screen. Using augmented reality tracking, ArchieMD's 3D imagery of the body's internal anatomy was superimposed over the view of the user, providing additional 3D didactic information while using a task trainer manikin. One of the key limitations of the approach is that it provides a 3rd person Point-of-View (POV) instead of a 1st person POV. While the 3rd person POV approach has utility for group activities and demonstration, it is of lesser value to the individual practicing the procedure. The use of a 1st person POV would enable seamless integration into medical training. This could be enabled through the use of augmented reality glasses or goggles. Recently, a number of exciting developments have occurred with respect to optical see-through augmented reality glasses and goggles. Phase I SBIR project, ArchieMD developed a 1st person POV MR trainer for Central venous catheter placement, which was evaluated at the University of Michigan for preliminary utility and feasibility in medical education. During Phase II we will continue the work by completing the following specific aims.  Specific Aim 1: Continue development of the 1st person POV Mixed Reality trainer to include: o Expanding procedures to incorporates a full range of important medical procedures including IV and arterial line placement, neuraxial techniques (spinals, epidurals), peripheral nerve blocks, paracentesis, thoracentesis and chest tube insertion. o Optimize 1st person POV MR trainer for improved performance and alignment.  Specific Aim 2: Conduct iterative usability testing with the expanded 1st person POV Mixed Reality trainer  Specific Aim 3: Conduct a randomized controlled trial to assess the ability of the 1st person POV Mixed Reality to improve procedural skills, as compared to traditional manikin trainers.

物理对人口比率开始稳定，预计将在 美国较早的人（以及医学上需要更多的需求）人口正在上升。那，身体劳动力 可能无法满足美国人口的需求。实际上，在2020年，美国可能会面对 45,400名初级保健医师和46,100名医学专家的短缺 - 总计91,500 医生太少。其他项目估计，美国医师的供应甚至可能减少 较低，到2020年的短缺高达200,000超过200,000。此外，质量时间的数量 医学生必须学习程序引起了研究人员的关注。大师有 正在开发医学模拟增强现实系统以结合多媒体 具有Manikins的技术可以使内部解剖学覆盖医疗教练。大师 根据人类Manikin任务培训师与2D和3D相结合开发了该技术 屏幕上显示的解剖视觉模型。使用增强现实跟踪，Archiemd 人体内部解剖结构的3D图像是在用户视图上叠加的 在使用任务培训师Manikin的同时，还提供其他3D教学信息。关键之一 该方法的局限性是它提供了第三人称观点（POV），而不是第一个 人POV。虽然第三人称POV方法具有小组活动的实用性，并且 演示，对于个人实践，它的价值较小。使用第一 PON POV将使无缝集成到医疗培训中。这可以启用 通过使用增强现实眼镜或护目镜。最近，许多令人兴奋的 在光学透明的增强现实眼镜和 风镜。第一阶段SBIR项目，Archiemd开发了Central的第一人称POV MR Trainer 静脉导管放置，在密歇根大学进行了评估 效用和医学教育的可行性。在第二阶段，我们将继续工作 完成以下特定目标。 具体目标1：继续开发第一人称POV混合现实教练 包括： o扩展程序以纳入一系列重要的医学 包括IV和动脉线位置在内的程序，神经氧化技术 （脊柱，硬膜外），外周神经阻滞，超牙术，胸腔化和 胸管插入。 o优化第一人称POV MR Trainer，以提高性能和对齐方式。 具体目标2：与扩展的第一人称POV进行迭代可用性测试 混合现实教练 具体目标3：进行随机对照试验以评估第一的能力 与传统的人相比 Manikin培训师。
