便携X光机工作原理
Working principle of portable X-ray machine
主要是影像增强器是运用(MCP)微通道板具有电子倍增作用,实现将电子图像信号成倍放大的作用.在手提式X光机产品上的作用:以极低的X射线电子流透射过患者受伤部位,成像电子打在影像增强器接收靶上,通过MCP微通道板增强信号,将微弱的信号成数十倍的放大成强信号,在通过光栅将X光转化为可见光,形成人眼可分辩的有价值的足够清晰的图像.由于球管发出的X射线强度控制在低的安全范围内,所以对人体几乎没伤害,同时该机整体重量也很低,仅3.6公斤,实现手提化.
The main function of the image intensifier is to use the MCP microchannel plate to multiply the electronic image signal. The function of the portable X-ray machine product is that the extremely low X-ray electron flow passes through the injured part of the patient, and the imaging electron hits the receiving target of the image intensifier to enhance the signal through the MCP microchannel plate, The weak signal is amplified into a strong signal by tens of times, and the X-ray is converted into visible light through grating, forming a valuable and clear image that can be distinguished by human eyes. Because the intensity of X-ray emitted by the ball tube is controlled in a low safety range, it is almost harmless to human body. At the same time, the overall weight of the machine is also very low, only 3.6 kg, which is portable
