This invention proposes a method of suppressing the noise of the magnetic resonance images reconstructed from data collected by a multi-channel radio-frequency (RF) receiver coil array. The method comprises 1) measuring the k-space data from each channel of the RF coil array of a multi-channel MRI system, and 2) estimating and applying a linear relationship between the k-space data from different channels of the RF receiver coil array to enforce the k-space data consistency and subsequently to suppress the noise of the k-space data. This method of enforcing the k-space data consistency can also integrate the image sparsity feature to further suppress the noise and to enhance the quality of the reconstructed images.本發明提供一種重建多通道核磁共振影像的方法,包含:量測多通道核磁共振影像系統射頻相列線圈每一通道之k-空間數據;利用不同通道之k-空間數據之線性關聯,以強化k-空間數據之一致性,達到抑制k-空間數據雜訊的目的。在強化k-空間數據之一致性的同時,也可強調最後成像的稀疏性,藉此所重建出的影像可進一步抑制雜訊與提高影像品質。
