Project Summary The use of ultrasound for interventional guidance has expanded significantly over the past decade and has become an important tool in clinical specialties such as Anesthesia, Emergency Medicine and Sports Medicine. In interventional ultrasound, there are significant challenges introduced by the necessity of simultaneously visualizing the target and the needle with a single B-mode probe, keeping the nondominant hand steady while finding the correct trajectory of the needle in the dominant hand. The resulting alignment problem (probe, instrument, target) is a different skill problem than identifying structures in ultrasound and requires specialized training. Current training systems do not provide suitable information to aid the novice user in developing key hand-eye coordination skills and their retention. For this reason, we propose to design the EDU –comprised of an Interson ultrasound, a tablet computer with guidance software, a CGM Optical Head with tiny video cameras, and a CGM custom nerve block phantom-- as a learning platform for developing key skills in needle acquisition, accuracy of needle placement, and understanding needle-to-ultrasound-plane orientation. The use of tiny video cameras on the ultrasound enable computer algorithms to compute the trajectory differences between an experienced user performing one of the regional blocks and a student’s attempt. The differences between the paths to the target allow some quantification of the skills, which may be helpful in giving feedback to the student during the semester, and perhaps also to develop a benchmark for CME courses. A second aim of this proposal is to study whether learning with needle-guidance software is beneficial to student skill acquisition and/or confidence. This proposal would study a cohort of student registered nurse anesthetists during a semester course teaching five progressively more difficult nerve blocks/procedures. With this novel system, quantifiable metrics can be harnessed to demonstrate whether learning with guidance is helpful, even when the guidance is removed, and whether it can lead to more consistent procedures across students. Using proprietary custom- made phantoms, the progressive difficulty levels of the five procedures can show whether guidance can be more helpful in more difficult blocs or if it can help in all.

项目概要 在过去的十年中，超声介入引导的应用显着扩大，并且 成为麻醉、急诊医学和运动医学等临床专业的重要工具。 在介入超声中，由于需要同时进行超声检查，因此带来了重大挑战 使用单个 B 模式探头可视化目标和针，同时保持非惯用手稳定 找到惯用手中针的正确轨迹由此产生的对准问题（探针， 仪器、目标）与超声结构识别不同，是一个不同的技能问题，需要专门的技术 当前的培训系统没有提供合适的信息来帮助新手用户开发密钥。 因此，我们建议设计 EDU，其中包括： Interson 超声波、带有引导软件的平板电脑、带有微型摄像机的 CGM 光学头、 以及 CGM 定制神经阻滞模型——作为培养针采集关键技能的学习平台， 针放置的准确性，以及了解针到超声平面的方向 使用小视频。 超声波上的摄像头使计算机算法能够计算物体之间的轨迹差异 有经验的用户执行区域块之一和学生的尝试。 通往目标的路径允许对技能进行一定程度的量化，这可能有助于向学生提供反馈 学期期间，或许还可以制定 CME 课程的基准 本提案的第二个目标。 是研究使用针引导软件学习是否有利于学生技能的获得和/或 该提案将在一个学期内研究一批注册护士麻醉师学生。 通过这个新颖的系统，可量化的教学课程五种逐渐困难的神经阻滞/程序。 可以利用指标来证明在指导下学习是否有帮助，即使指导是 删除，以及它是否可以使学生之间使用专有的定制程序更加一致。 制作模型时，五个程序的难度等级可以显示是否可以进行更多指导 对更困难的集团有帮助，或者是否对所有集团都有帮助。
