摘要
在数字X线摄影中,散射线造成了图像对比度的损失、噪声的增加,是使图像质量恶化的主要原因。为了提高数字X线图像的质量,必须采取有效措施减少散射线,减小对比度的损失。除了硬件减少散射线的方法外,国内外学者对数字X线摄影中散射线计算机补偿方法做了一些研究,本文对散射线计算机补偿方法的研究进展作一综述。
Scatter radiation is a major reason of image degradation in digital radiography ,the degradation can be characterized by a loss of contrast and an increase in noise. In order to improve the image quality, decrease the loss of contrast,effective measures must be taken. In addition to the physical methods,much research has been done on computerized scatter compensation in digital radiography .This article reviews the development situation in this field.
