Embodiment Construction
[0036] like figure 1 As shown, the present invention discloses a fast diffusion tensor imaging method under the framework of compressed sensing. For M levels, each level has L gradients, that is, M*L images are reconstructed altogether, and each level includes Perform the following steps:
[0037] In step S1, initialize the sampling mask mask1 corresponding to the first diffusion gradient, and use a ray-shaped sampling trajectory;
[0038] In step S2, the sampling mask mask1 corresponding to the first diffusion gradient is rotated by a fixed angle to obtain the sampling mask mask2 corresponding to the second diffusion gradient, and the sampling mask mask2 corresponding to the second diffusion gradient is rotated in the same direction Rotate the same fixed angle to obtain the sampling mask mask3 corresponding to the third diffusion gradient, and so on to obtain a total of L sampling masks, and obtain each measurement matrix Φ according to each sampling mask mask i , the L is ...
