PF-FICOTA-SENSE: 一种MRI快速重构方法

How to realize rapid magnetic resonance imaging (MRI) is the key to the development and applications of MRI. The existing rapid MRI imaging technology still has much room for improvement in imaging rate and imaging quality. Based on Contourlet which is used to transform the sparse representation of magnetic resonance images, this paper proposes a combined MRI reconstruction method named PF-FICOTA-SENSE that is combined with the traditional PF-CS-SENSE framework. Considering the combination of MRI sampling mode, the symmetry of the low frequency data and Contourlet's ability to express curve contours, a fast combined MRI method for direct zero-filled Fourier reconstruction of low-frequency parts is proposed based on the proposed PF-FICOTA-SENSE. The contrast experiments show that the proposed method can achieve better performance in terms of MRI reconstruction speed and reconstruction quality.
