Abstract:
Because X-ray digital tomosynthesis (DTS) imaging principle is different from that of CT, DTS has better spatial resolution than that of CT in sagittal and coronal planes, and since DTS is reconstructed to generate"layer" images, its power in the aspect of distinguishing 3D tissue structures is superior to that of general X-ray photography, so DTS can provide 3D information for clinical diagnosis; its radiation dose is markedly lower than that of CT. In recent years, DTS has made progress in the application of skeletal system imaging; the research progress and the possible direction of future application of DTS in bone fracture diagnosis, fracture healing estimation, vertebral bone quality assessment and fracture risk prediction, joint dislocation diagnosis, bone erosion evaluation and postoperative arthroplasty assessment were summarized.
