A Simulation Study of Dynamic MRI Based on Partially Separable Functions and Keyhole Techniques

摘要：

The partially separable function (PSF) model can significantly improve MRI spatial and temporal resolutions. However, the pre-data acquisition of PSF is very time-consuming in practical. To overcome this limitation, in this paper we proposed using keyhole for fast pre-data acquisition of PSF. The simulation results showed that the pre-data acquired by keyhole can be properly processed by partially separable functions, and the MR images can be reconstructed in high quality without any motion artifacts. This result demonstrated the potential of dynamic MRI by combine use of PSF and keyhole techniques.
