Abstract
The invention relates to a collimating slit module, which is made of a high-density metal material and comprises a collimating part, wherein a plurality of collimating slits are integrally arranged on the collimating part. The invention also relates to another collimating slit module assembly, which is assembled by a plurality of collimating slit modules, wherein the distance between adjacent collimating slits of two adjacent collimating slit modules is the same as that between adjacent collimating slits on a collimating slit module. The invention also relates to a manufacturing method for the collimating slit module, which comprises the following steps of: providing a body made of the high-density metal material; and machining the plurality of collimating slits with a predetermined size on the body. The collimating slit module of the invention has the advantages of convenient machining and high precision, and the manufacturing method is also suitable for manufacturing the collimatingslit module with high precision and large size. In addition, the invention also relates to a collimator and a radiation imaging check system using the collimator.
Description
technical field [0001] The invention relates to a radiation detection device using an accelerator and an X-ray machine as a radiation source, and belongs to the technical field of radiation detection. More specifically, the invention relates to a collimation seam module made of high-density metal materials and a manufacturing method thereof. And a collimator with the collimation slit module and a radiation imaging inspection system with the collimator. Background technique [0002] In existing large-scale container detection, industrial CT, medical CT and other radiation imaging systems, according to the detection needs, a single or several collimation slot modules are installed in groups at the front end of the line array detector to shield scattered rays and reduce the aperture width of the detector. Increase spatial resolution, thereby improving inspection image quality. [0003] The collimation slit module is mainly used to shield the scattered rays of radiation sources...
