简单SENSE图像重建，即使通过反傅里叶变换重建出最终图像(The data was acquired from 4-channel array coil using EPI sequence (2-shot, matrix: 64X64, TE: 50 ms) at a 1.5T scanner. The code estimates the coil sensitivity profiles directly from the image with anatomical contrast by low-pass smoothing. Subsequently, k-space data were decimated to simulate 2.0-fold acceleration (R=2.0). Finally, using least-squares estimate, the reconstructed full-FOV spin density image is obtained)

三维时域有限差分程序，cpml吸收边界，介质表面采用网格均分技术(Three-dimensional finite-difference time-domain algorithm, CPML absorbing boundary, sharing media surface using grid technology)

Low-density parity-check (LDPC) codes have recently emerged due to their excellent performance. However, the parity check (H) matrices of the previous works are not adequate for hardware implementation of encoders or decoders. This paper proposes a hybrid parity check matrix which is efficient in hardware implementation of both decoders and encoders. The hybrid H-matrices are constructed so that both the semi-random technique and the partly parallel structure can be applied to design encoders and decoders.
