Embodiment Construction
[0021] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
[0022] Digital radiography (DR) is currently the most widely used X-ray imaging equipment. For surgical positioning scenarios, mobile DR or C-arm is generally used. Portable DR such as orthopedics or interventional therapy has high spatial resolution and imaging speed. Fast, low price, less radiation, etc., but it can only provide two-dimensional tissue stack images, often unable to directly observe tiny lesions with small differences in tissue density. On the other hand, due to respiratory movement, setup errors, and posture differences, there are often large differences between intraoperative DR photography and preoperative diagnostic imaging, and the spatial mapping relationship between medical 3D images and 2D proje...
