Sparse MRI has been introduced to reduce the acquisition time and raw data size by significantly undersampling the k-space. We propose an interpolation method to improve the signal to noise ratio or imaging speed for multi-slice two-dimensional MRI. The raw data of each slice is multiplied by a weighting function and then used to estimate the missed k-space data of the neighboring slice, which helps improve the SNR of the neighboring slice. In-vivo MR of human feet has been used to investigate the feasibility of the proposed method, showing obvious improved SNR of the neighboring slice.
