Description

technical field [0001] The invention relates to a device in the technical field of medical devices, in particular to a multi-degree-of-freedom cone-beam CT imaging system. Background technique [0002] X-ray cone-beam CT installed beside the treatment bed is an important means of realizing image guidance today. At present, the scanning trajectory of the cone beam CT system is limited, and generally only a single scan of a circular trajectory is performed, so the longitudinal space coverage is low, generally about 15 cm, and the non-coplanar scanning strategy cannot be realized. The low longitudinal coverage leads to the use of "step-exposure" mode in the treatment of head and neck tumors, that is, after completing a circular trajectory scan, the bed is translated to the next body position, and another scan is performed to cover the entire head and neck. This will double the radiation dose, and the subsequent image stitching and fusion is also very cumbersome. However, the ...
