Embodiment Construction
[0030] The present invention will be described in detail below in combination with specific embodiments.
[0031] The present invention is based on the radiation imaging concept and improves and optimizes the radiation imaging imaging system for resolution, which is suitable for accurate imaging of clinical or experimental animals. like figure 1As shown, the radiation imaging system provided by the present invention includes an intensifying screen radiation conversion film 1 (referred to as film), an imaging darkroom 2 and an optical imaging hardware system (comprising an EMCCD camera 3 and a computer 4) with a parallel aperture collimator. ). The film is composed of a clinically used X-ray rare earth intensifying screen (calcium tungstate medium-speed medical intensifying screen) and a parallel-hole collimator made of flexible lead material. The parallel-hole collimator can shield scattered radiation. Increase the display resolution. The imaging darkroom is manufactured ac...
