Problems solved by technology
For example, in the detection process, the resolution required for objects of different sizes may be different, or the same detection object needs to be partially enlarged, the corresponding resolution needs to be adjusted accordingly, and the existing particle direct projection imaging system cannot meet the requirements. For the above requirements, it is urgent to develop a particle projection imaging system with adjustable resolution

The invention discloses a resolution-adjustable particle projection and imaging system, comprising a support frame, a rack, a lifting mechanism, a particle generator, a particle detector, and a to-be-detected object placement platform for placing the object to be detected. The particle generator and the particle detector are fixed on the rack and are oppositely arranged; the to-be-detected objectplacement platform is arranged between the particle generator and the particle detector; and the rack is arranged on the supporting frame. The rack can move up and down along the support frame drivenby the lifting mechanism, so as to drive the particle generator and the particle detector to move up and down. According to the resolution-adjustable particle projection and imaging system, the resolution adjustment of the particle direct projection and imaging system can be realized; multiple purposes can be achieved by the invention; and the use efficiency of the particle direct projection and imaging system is improved.
Description
technical field [0001] The invention relates to the field of particle projection imaging equipment, in particular to a resolution-adjustable particle projection imaging system. Background technique [0002] Particle imaging is more and more widely used in medical detection, industrial detection, security inspection and other fields. Its working principle is to place the object to be detected between the particle source and the particle detection device, and the object is imaged on the detection device after being penetrated by the particles. [0003] In the existing particle direct projection imaging system, the relative positions of the particle source, the object to be detected and the particle detection device are fixed. Therefore, its imaging resolution depends on the intrinsic resolution of the particle detection device. Without changing the detection device or system structure, its resolution is fixed and cannot be adjusted. [0004] However, in practical applicatio...
