Abstract

In order to improve the imaging quality of X-ray and reduce the effects of X-ray and scatter line on image, the adoption of X-ray collimator is the most effective method. MCP collimator in parallel structure can effectively reduce the ratio of X-ray and scatter line to reach on image plane, and reduce the atomization degree of images, so as to improve the image contrast. Through the establishment first-order radiation transmittance model of MCP collimator, test the performance of MCP collimator, it is prove that the MCP collimator can be used in the imaging system that consists of proximity of X-ray image intensifier, first-order radiation transmittance calculation formula of MCP absorption type collimator in parallel structure is reduced, obtain the transmittance distribution non cosine curve distribution of MCP collimator through calculating.
