摘要 本文提出了一种线扩散函数,用以从理论上估算X线管的MTF。结果表明较脉冲函数更加实际,而且在空间频率较大的区域也较准确。 , In this paper ,a line spread function is presented to calculate the MTF of focus theoretically. The results showed that the sample function is more approximate to the MTF of focus , and in the region of large space frequency it is more accuracy.
