Low Dose Weight-Bearing Computed Tomography Scanner Scope of Project:Cone beam computed tomography (CT) scanners enable internal volumetric imaging of the extremities in weight bearing and non-weight bearing configurations. Three-dimensional imaging of bones with lower radiation doses than traditional CT is performed using a rotating cone beam X-ray. Configurable systems enable imaging of various joints of the upper and lower extremities.General Description:The weight bearing CT scanner will be used to visualize the bony geometry in the joints of the upper and lower extremities, with the knee joint of particular interest. Images will also be segmented to produce 3D models of joint geometry for further analyses and to develop personalized computational models. For this, export to Digital Imaging and Communications in Medicine (DICOM) format for use with typical segmentation software (e.g., Materialise Mimics, 3D Slicer) is necessary. A key use of the equipment will be to produce images for tracking biplanar videoradiography data. Therefore, the resolution of a pixel size of at least 0.5 mm and a slice thickness of at most 0.625 mm is required (Welte et al., 2022, doi:10.3791 63535) to allow for natural standing during imaging and reduce radiation dose to the participants when scanning both lower limbs, the ability to perform bilateral scans of the lower extremities is required.Mandatory Requirements: 1. Weightbearing CT Scanner:1.1 Must fit in a 3x3 m footprint.1.2 Must be capable of producing scans with an in plane resolution ...
