To further suppress the motion artifacts and improve the MRI image quality, this paper presents an improved PROPELLER algorithm using frequency domain and image domain information to estimate motion parameter based on wavelet transformation. Different from the conventional PROPELLER algorithm, in the improved algorithm, the temporary image reconstruction of… (More)
Parallel Magnetic Resonance Imaging (PMRI) has become a powerful technique to speed up magnetic resonance data acquisition by multiple phased array coils in recent years. The coil sensitivity is a significant factor in the MRI image reconstruction, however it is generally unknown in advance, therefore how to estimate the coil sensitivity accurately is an… (More)
