DEVICE: Halifax Imaging Kit (00628451892021)

Device Description: The Halifax Imaging Kit is part of the SR Suite product line, provides an alternative path to creating an SR Suite. The Halifax Imaging Kit is comprised of FDA cleared or certified X-Ray components integrated into an existing digital radiography room already containing an FDA cleared x-ray imaging system to form an SR Suite. The exposures of the Halifax Imaging Kit and the existing DR system are synchronized by replacing the trigger switches of the two systems with the Halifax Synchronization Switch. The Halifax Synchronization Switch ensures the two X-Ray imaging systems fire simultaneously, providing a pair of X-Ray images from two different perspectives to be taken at the exact same time. This process allows for Roentgen Stereophotogrammetric Analysis (RSA) or stereo orthopaedic radiography (SOR). RSA is a stereo x-ray technique that enables measurements more accurate and precise than single plane radiography based on phantom studies. The increased level of precision enables measurement of implant stability.
