SimpleSENSEreconstruction
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)

GLCM_Features1
GLCM_Features1 helps to calculate the features from the different GLCMs
that are input to the function. The GLCMs are stored in a i x j x n
matrix, where n is the number of GLCMs calculated usually due to the
different orientation and displacements used in the algorithm. Usually
the values i and j are equal to NumLevels parameter of the GLCM
computing function graycomatrix(). Note that matlab quantization values
belong to the set {1,..., NumLevels} and not from {0,...,(NumLevels-1)}
