During orthopaedic surgeries, surgeons use X-ray imaging to detect bone and implant positions with a mobile C-arm (sonamed due to the C shape, with the X-ray source on one side and the detector on the other). This is essential to get a visual sense of the locations of the instruments and implants with respect to the anatomy of the patient. There is huge untapped potential for using these devices beyond their current use for improving the accuracy of the surgery and reducing the surgical time and radiation dose. If fitted with appropriately accurate and low-cost technology, these devices can provide two very important advantages that can revolutionize how these very broadly available devices are used. First, they can provide unprecedented capability for accurate measurements from large images of the anatomy and allow assessment of the position of the bone and instruments in three dimensions. This is critical for many surgeries because incorrect placement of implants can lead to poor outcome for the patient or a longer time under anesthesia. Second, the new technology can help the surgical staff to find an image of interest very quickly without trial and error and the waste of costly surgical time. With current systems, it can take considerable time to orient the C-arm properly because of the difficulty of communicating between the surgeon and the C-arm operator (radiation technologist). Numerous X-rays are taken during this time, exposing the patient and surgical staff to radiation. To address these, our multi-disciplinary team of experts from UBC, UofC, and BCIT will collaborate to combine their existing innovative technologies to develop and validate novel surgical imaging equipment that can be implemented in all operating rooms across Canada to offer better care for the patients. We will have support from three Canadian companies for the next stage of commercialization and business development of the product.

在整形外科手术中，外科医生使用X射线成像来检测骨骼和植入物位置，并使用移动的C形臂（声标 由于C形，X射线源在一侧，探测器在另一侧）。这是获取图像的关键 器械和植入物相对于患者解剖结构的位置感。有巨大的未开发的 使用这些器械超出其当前用途的潜力，以提高手术的准确性并减少 手术时间和辐射剂量。如果配备适当的精确和低成本的技术，这些设备可以提供两个 这些非常重要的优点可以彻底改变这些非常广泛可用的设备的使用方式。首先，他们可以提供 前所未有的能力，从解剖结构的大图像进行精确测量，并允许评估 骨和器械的三维位置。这对于许多手术来说是至关重要的，因为不正确的放置 植入物可能导致患者的不良结果或更长的麻醉时间。其次，新技术可以帮助 手术人员可以非常快速地找到感兴趣的图像，而无需反复试验和浪费昂贵的手术时间。与 在当前的系统中，由于通信困难，可能需要相当长的时间来正确地定向C形臂 外科医生和C形臂操作员（放射技师）之间的沟通。在此期间拍摄了许多X光片， 病人和手术人员的辐射。为了解决这些问题，我们来自UBC，UofC和BCIT的多学科专家团队 将合作联合收割机，结合现有的创新技术，开发和验证新型外科成像设备 可以在加拿大所有的手术室实施，为病人提供更好的护理。我们会得到支持 三家加拿大公司为该产品的下一阶段商业化和业务发展提供资金。
