摘要
ZKXZ -80数字化X线装置的成像原理是由影像增强电视系统将X线转化成可见光 ,再由电荷耦合器件(CCD)将可见光转化成视频信号。经图像卡A/D转换成数字化矩阵图像 ,因此成像因素kV、mA。
The imaging principle of ZKXZ-80 digital X-Ray machine is that a X-ray image represented a radiography is changed into light by using an enhancing TV system, then the electronic coupling device (CCD) turns the light into video frequency signal, and is transformed into a digital matrix image with image A/D converter. So the key of quality control is to specify the imaging factors reasonably, such as kV, mA, D and S.
