Abstract

The invention discloses a multifunctional cone-beam CT imaging system, and belongs to the technical field of CT imaging. The multifunctional cone-beam CT imaging system comprises a main rotating table, an auxiliary rotating table, a flat panel detector frame and an X-ray light source, wherein the main rotating table is provided with horizontal moving devices, the auxiliary rotating table is provided with a vertical moving device, and the flat panel detector frame is provided with a horizontal transverse moving device. The central axis of the main rotating table coincides with the central axis of the auxiliary rotating table. The two horizontal moving devices at the two ends of the main rotating table are connected with the flat panel detector frame and the X-ray light source respectively. The multifunctional cone-beam CT imaging system can achieve high-precision movement with the six degrees of freedom, can achieve two scanning modes of cone-beam CT imaging device rotation and imaging object rotation, the two scanning modes of axis scanning and spiral scanning, and the functions of online real-time adjustment of imaging geometric parameters, has the outstanding advantages of being large in scanning range, flexible and variable in imaging geometric parameters and the like and is applicable to application occasions of cone-beam CT imaging experiments and CT detection for various purposes.

Description

technical field [0001] The invention relates to a device in the technical field of medical devices, in particular to a multifunctional cone-beam CT imaging system. Background technique [0002] The medical cone-beam CT imaging system using large-area flat-panel detectors and kilovolt-level X-ray tubes has an open hardware structure, which is more portable and flexible than traditional multi-row CT, and is easy to integrate with surgical and radiotherapy application environments. Treatment monitoring features, has become a mainstream image-guided technology. Pre-clinical experiments of medical cone-beam CT imaging systems and methods based on traditional desktop platforms, including phantom experiments and small animal experiments, have a single imaging mode, and the imaging mode in which the imaging object rotates around the central axis does not conform to the actual work of medical equipment model etc. The multifunctional cone beam CT imaging system for cone beam CT pre-...
