Code for reproducing the Figures in "Aliasing-free Reduced Fielf-of-View Parallel Imaging"
This package relies on the following external packages:
- arrayShow - displaying multi-dimensional image array (https://github.com/tsumpf/arrShow)
- ESPIRiT - MATLAB ESPIRiT calibration and utility functions (https://people.eecs.berkeley.edu/~mlustig/software/SPIRiT_v0.3.tar.gz)
- BART - C ESPIRiT calibration and Compressed Sensing Parallel Imaging reconstruction (https://github.com/mrirecon/bart)
Figure 1 - 2D imaging with 1D Reduced FOV Parallel Imaging (MATALB)
Figure 2 - 3D imaging with 2D Reduced FOV Parallel Imaging (MATLAB, a 2D slice extracted from 3D kspace)
Figure 3 - 3D imaging with 2D Reduced FOV Compressed Sensing (MATLAB, a 2D slice extracted from 3D kspace)
Figure 4 - 2D imaging with 1D Reduced FOV Wave Encoding (MATLAB)
Figure 5 - 3D imaging with 2D Reduced FOV Wave Encoding (BART)
Response Figure - Soft-SPIRiT (two steps: applying Soft-SENSE after SPIRiT reconstruction)
Data Description:
All experimental datasets (Total 3.4 GB) can be downloaded from (https://pan.baidu.com/s/1kbro9HhZuTGbHlnecq_kHQ using PWD: ruj8) The data should be stored into the folder named as /data.
The experimental dataset for Figure 1,2,3 can be downloaded separately from https://pan.baidu.com/s/1qOgFH1Bkbx_BVT89ndGMRg using PWD: aq8a (72 MB).
The experimental dataset for Figure 4 can be downloaded separately from https://pan.baidu.com/s/1iOzdXVpotZweW6dKs6BDNg using PWD: rvt6 (150 MB).
The experimental dataset for Figure 5 including two 3D data of size of 2.2 GB (PI 2x2) and 1.2 GB (reduced FOV 2x + PI 2x) respectively.
The implementations of SoftSENSE:
SoftSENSE_Direct - SoftSENSE reconstruction for regular downsampling by pixel-by-pixel direct inversion
cgSoftSENSE_Cartesian - SoftSENSE reconstruction for 2D/3D Cartesian imaging with/without reduced FOV imaging
cgSoftSENSE_Wave - SoftSENSE reconstruction for 2D/3D Wave imaging with/without reduced FOV imaging
cgSPIRiT_Cartesian - SPIRiT reconstruction for 2D/3D Cartesian imaging with/without reduced FOV imaging
cgSPIRiT_Wave - SPIRiT reconstruction for 2D/3D Wave imaging with/without reduced FOV imaging
