| 摘 要： | 本文研究了不同ｋ空间信号的多次平均对图像信噪比的影响，我们证明，那些在ｋ空间信号具有相同平均次数的图像具有最大的信噪比．本文为这一结论进行了理论分析，并进行实验．实验结果与我们的理论分析几乎完全一致．

| Abstract: | The influences of different k-space signal averaging to signal-to-noise ratio are studied.It is proved that the image with the uniform k-space signal averaging has the best signal-to-noise ratio.A theoretical explanation for this conclusion is offered. The agreement between expermental results and theoretical prediction is excellent. |
