We propose here a combination of the Karhunen-Loeve Transform filter and prolonged data acquisition to improve the SNR of dynamic cardiac MR images. The temporal redundancy of real-time cardiac MR images increases with the number of cardiac cycles included, which can improve the performance of the KLT filter. In vivo experimental study showed that it is a practical way to recover SNR.
