摘要
研究了在工业X射线成像领域,放大倍数、管电压、管电流、曝光时间等参数与图像质量的相关性,探讨了图像质量最优时成像参数的选取。试验结果表明:在不考虑有效剂量的前提下,采用高放大倍数、低管电压、大电流,可以获得更好的图像质量。
The relationship between magnification ratio,tube voltage,tube current and exposure time and image quality is studied.The selection of imaging parameters for image quality optimization is explored.The results show that high magnification,low tube voltage and high current can obtain better image quality under the contition of being without considering effective dose.
