摘要

针对混合成像过程中磁共振图像被T2效应和测量噪声降低的问题，提出了增强的方法。利用维纳滤波和线性预测(LP)技术分别进行全局和局部T2校正。这种组合技术在校正T2失真和降低测量噪声方面的有效性得到了证明

T2 restoration and noise suppression of hybrid MR images using Wiener and linear prediction techniques

The authors address the problem of enhancing magnetic resonance (MR) images degraded by T2 effects and measurement noise in hybrid imaging process. Wiener filtering and the linear prediction (LP) techniques are utilized to perform global and local T2 corrections respectively. The effectiveness of this combined technique in correcting T2 distortions and reducing measurement noise is demonstrated.<>
