Description

Technical Field

[0001] The utility model relates to the technical field related to medical radiographic imaging, in particular to a novel O-ring imaging system for multi-degree-of-freedom non-coplanar imaging. Background Art

[0002] New CT scans are spiral scans and were introduced in the early 1990s. Non-spiral scans are usually referred to as axial or sequential scans. Modern CT scans can be performed in both axial and spiral scans. Spiral CT refers to the third generation of CT, in which both the tube and detector can rotate. Cables move with the tube and detector, providing power and returning data. In an axial scan, the X-ray tube will rotate 360° around the patient, and image-guided radiation therapy (IGRT) uses soft tissue or implanted markers to ensure that the target area can be accurately located before treatment.

[0003] The existing technical solutions have the following defects: the C-arm imaging system is one of the most commonly used imaging systems. Due to its C-shaped structure, the imaging angle is generally about 190°, and it cannot rotate around the patient for imaging. In the conventional O-ring imaging system, one ring can rotate, and the tube and the plate are fixed on this moving ring. The position is relatively fixed, and the imaging area is also fixed and relatively small. In the O-ring imaging system with a double-ring structure, the tube and the plate are installed on two rings and move independently to form a large field of view. The structure is complex and the control is cumbersome. Therefore, we propose a new multi-degree-of-freedom non-coplanar imaging O-ring imaging system to solve the above problems.
