Image-guided musculoskeletal needle placement procedures, such as facet joint and nerve block injection, epidural blocks, arthrography injections, biopsies and vertebroplasty are performed by the millions in Canada and around the world. Computed tomography is widely used in musculoskeletal applications; magnetic resonance imaging has become the gold standard in imaging a variety of osseous and joint conditions. To date, there has been limited success in needle guidance using these imaging modalities. Accurate, simple, intuitive and affordable technology for image-guided needle placement procedures for average care facilities does not exist. A concurrent challenge will be to teach these procedures in a manner that parallels practice. The mobile image overlay system (MIOS) we propose will reflect a display image by a semitransparent mirror so that the image, in correct pose and magnification, appears floating inside the patient. We expect to improve the accuracy of needle insertion, providing the operator with the best chance of first pass success. Beyond simplicity and low cost, MIOS will provide a view of the target anatomy at the needle tip for multiple observers, which makes it an ideal hands-on teaching tool. When the MIOS is detached from clinical imaging scanners, the identical image guidance experience can be provided in instructor-led or self-guided simulation training. MIOS promises to enhance the skill among future practitioners and, as a result, improve patient outcomes. Also, using the current installed base of imaging scanners, this effective, simple, affordable needle placement guidance system can increase the number of access points for procedures, reducing wait times. In the long-term, MIOS can be generalized to in-room image-guided needle placement in diagnostic or therapeutic interventions like cancer biopsy or tissue ablation with immediate application in head and neck procedures, along with appropriate hands-on teaching and training tools.

图像引导的肌肉骨骼针放置程序，如小关节和神经阻滞注射，硬膜外阻滞， 在加拿大和世界各地，有数百万人进行关节造影注射、活组织检查和椎体成形术。 计算机断层扫描广泛应用于肌肉骨骼应用;磁共振成像已成为黄金 在各种骨和关节状况的成像中是标准的。迄今为止，在针引导方面的成功有限 使用这些成像模式。准确、简单、直观且经济实惠的图像引导针放置技术 一般护理设施的程序不存在。同时面临的一个挑战将是以一种 这与实践是平行的。我们提出的移动的图像覆盖系统（米奥斯）将通过一个非透明的反射器来反射显示图像 镜子，使图像，在正确的姿势和放大，似乎浮动在病人体内。我们期望 提高针头插入的准确性，为操作者提供首次成功的最佳机会。超出 简单和低成本，米奥斯将为多个观察者提供针尖处目标解剖结构的视图， 它是一个理想的动手教学工具。当米奥斯与临床成像扫描仪分离时， 可以提供由教师主导或自我指导的模拟培训方面的经验。米奥斯承诺提高 未来的从业者，并因此改善患者的结果。此外，利用目前安装的成像扫描仪基础， 这种有效的、简单的、可负担得起的针放置引导系统可以增加进入点的数量 减少等待时间。从长远来看，米奥斯可以推广到室内图像引导针放置， 诊断或治疗干预，如癌症活检或组织消融，立即应用于头部和颈部 程序，沿着适当的实践教学和培训工具。
