The invention provides a CT scanner filter switching device which comprises a drive rod, a chuck plate, a jacking rod, a chuck plate spring, a guide block, a connecting baffle, an end cover, a baffle plate, a reset spring and a limiting plate, wherein an opening through groove is formed in one end of the drive rod, and the connecting baffle covers up the opening through groove; the guide block is arranged between the drive rod and the connecting baffle; the chuck plate is arranged in the opening through groove of the drive rod, and the jacking rod slides in the guide hole flexibly; a chuck plate spring is sleeved with one end of the jacking rod, and is limited between the outer edge of the chuck plate and the head of the jacking rod, the head of the jacking rod slides on the surface of the guide block under the effect of the chuck plate spring; the baffle plate is arranged at the other end of the drive rod, the drive rod slides in an end cap hole in a sliding manner, and the reset spring is connected onto the drive rod in a sleeved manner, and is limited between the end cover and the baffle plate; the limiting plate and the end cover are fixed on a collimator box body, and is connected with the baffle and the filter component. According to the invention, the problems of trivialness, high cost and the like in the switching process of a CT scanner filter can be solved.
Description
technical field [0001] The invention relates to the technical field of tomographic scanning medical equipment, and more specifically, to a filter switching device and a switching method of a CT machine. Background technique [0002] Computed tomography (Computer Tomography, referred to as CT) is widely used in medicine, industry and other fields. During the scanning process of the CT machine, in order to reduce the influence of scattered rays, a slice device is usually used. [0003] At present, the filter switching of the existing CT machine is generally driven by a special motor, and the filter is driven to move through a screw or a rack and pinion transmission. The structure is complex and the cost is high. [0004] In addition, the filter switching structure used in the existing MX&NeuViz16 products does not require a special motor drive. It needs to borrow the original two motors in the collimator to drive separately to complete the filter switching, and the operation ...
