Quantitative Intra-operative Imaging Tools for Applications in Orthopaedic Surgery

During orthopaedic surgeries, surgeons use X-ray imaging to detect bone and implant positions with a mobile C-arm (so named 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 great 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. 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, and numerous X-rays are taken during this time, exposing the patient and surgical staff to radiation.  To address these, Dr. Amiri's research work has been focused on developing innovative technologies that can be implemented in all operating rooms to offer better care for patients.

Dr. Amiri is a faculty member of the Biomedical Engineering Program and the Department of Mechanical Engineering, and a Research Associate at the UBC Department of Orthopaedics. He has a PhD from Queen’s University (Kingston, ON) in Mechanical Engineering, and Master's degree in Biomedical Engineering from AmirKabir University (Tehran, Iran). Dr. Amiri's general research interests are in Orthopaedic Biomechanics, Biomedical Imaging, and Design and Development of Medical Devices. His research program  focuses on quantitative intra-operative imaging and assessments, and image-based guiding devices for applications in Orthopaedics. Prior to his academic positions, he worked for a number of medical and engineering firms.
