The invention provides an image information acquisition device for a fluorescent screen detection platform, and the device comprises a mounting frame which is used for being placed on a fluorescent screen detection platform; a light-transmitting bearing plate which is used for placing a to-be-detected fluorescent screen for converting X-rays into visible light, and which is arranged on the mounting frame; a photosensitive panel which is used for converting visible light into an image electric signal, wherein the photosensitive panel is arranged on the mounting frame and located on the light-emitting side of the light-transmitting bearing plate, the photosensitive panel is provided with a plurality of photosensitive pixels distributed in an array mode, and each photosensitive pixel corresponds to one piece of coordinate information; an image processing circuit board which is used for converting the image electric signal into an image digital signal, wherein the image processing circuitboard is in communication connection with the photosensitive panel, and the image processing circuit board is arranged on the mounting frame and located on the side, back on to the light-transmittingbearing plate, of the photosensitive panel. According to the invention, the image digital signal corresponding to the to-be-detected fluorescent screen can be accurately acquired at one time.
Description
technical field [0001] The invention relates to the technical field of fluorescent screen detection, in particular to an image information acquisition device for a fluorescent screen detection platform. Background technique [0002] The medical see-through fluorescent screen detection system is to place the medical see-through fluorescent screen on the test frame inside the lead cabinet, and then use the X-ray machine inside the lead cabinet to emit X-rays to irradiate the fluorescent screen below. The lead cabinet plays the role of shielding X-rays, so that X-rays will not scatter into the surrounding environment and hurt the experimenters. [0003] At present, the detection method of the fluorescent screen is to put the cesium iodide screen to be tested on the test frame, with the carbon plate body facing up and the cesium iodide coating facing down, and divide the fluorescent screen into 9 areas for testing respectively, and use software to divide to correspond to the upp...
