An apparatus (18) configured to filter a magnetic resonance (MR) signal includes at least one electronic processor (24) programmed to: receive at least one MR signal (26) excited in an object disposed in an MR imaging apparatus (10); transforming the at least one MR signal with a coherence function representing the at least one MR signal as an instantaneous spectrum as a function of time; applying spectral filtering to the transformed at least one MR signal; and reconstructing at least one medical image from the filtered at least one MR signal. 一种被配置为对磁共振(MR)信号进行滤波的设备(18)包括至少一个电子处理器(24)，所述至少一个电子处理器被编程为：接收在被设置在MR成像设备(10)中的对象中激励的至少一个MR信号(26)；利用相干函数来变换所述至少一个MR信号，所述相干函数将所述至少一个MR信号表示为作为时间的函数的瞬时频谱；对经变换的至少一个MR信号施加谱滤波；并且根据经滤波的至少一个MR信号来重建至少一幅医学图像。
