Improving surgical outcomes with an augmented reality laser projection system

这项研究将在手术室使用激光投影增强现实系统，以改善计算机辅助手术的效果。这项工作有可能提供更准确和更容易的工具指导，更短的手术时间，并检测计算机上的手术计划和手术室中的患者位置之间的潜在危险的错位。我们将在拟议研究的开发和验证中瞄准计算机辅助骨科手术：患者在手术台上的位置与虚拟手术计划的对齐将比当前实践更可靠地计算。潜在危险的未对准将通过允许直观视觉确认对准的界面来检测。对准中的不确定性分布将投射到患者身上，供外科医生使用。 外科医生将提供一个使用界面来指导他们的工具。激光投影系统将由两名硕士生，一名博士生和一名博士后研究员使用。 这些人将在增强现实领域进行前沿研究，并直接应用于临床实践，通过与我们的外科同事互动，为他们提供跨学科技能。 在加拿大，这种高素质的人才严重短缺。我们希望我们的研究将导致新的指导技术在计算机辅助手术。 加拿大公司将从这项研究中受益，包括激光投影系统制造商Traxtal Technologies（多伦多，安大略）和手术工具跟踪设备制造商北方Digital（滑铁卢，安大略）。

This research will use a laser projection augmented reality system in the operating room to improve computer-assisted surgery outcomes. This work has the potential to provide more accurate and easier tool guidance, shorter operating times, and detection of a potentially dangerous misalignment between the surgical plan on the computer and the patient position in the operating room. We will target computer-assisted orthopaedic surgery in the development and validatation of the proposed research: The alignment of the patient's location on the operating table to the virtual surgical plan will be computed more reliably than current practice. Potentially dangerous misalignments will be detected through an interface that permits intuitive visual confirmation of the alignment. The distribution of uncertainty in the alignment will be projected onto the patient for use by the surgeon.  And the surgeons will be provided with an easier-to-use interface to guide their tools. The laser projection system will be used by two MSc students, one PhD student, and one postdoctoral fellow.  These people will perform leading edge research in augmented reality with direct applications in clinical practice, providing them with interdisciplinary skills through interactions with our surgical colleagues.  There is a critical shortage of such highly qualified people in Canada. We expect that our research will lead to novel guidance technology in computer-assisted surgery.  Canadian companies will benefit from this research, including Traxtal Technologies (Toronto, Ontario), the manufacturer of the laser projection system, and Northern Digital (Waterloo, Ontario), a producer of surgical tool tracking equipment.
