Abstract :
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
