Abstract:

A gradient-domain matrix elastic network infimal convolution regularization accelerated magnetic resonance parameter imaging method, and a terminal device and a computer storage medium. The gradient-domain matrix elastic network infimal convolution regularization accelerated magnetic resonance parameter imaging method comprises: reading K-space data of a group of under-sampled weighted graphs (S11); inputting the K-space data of the under-sampled weighted graphs into a pre-designed gradient-domain elastic network infimal convolution regularization model, and optimizing and solving using an ADMM algorithm, so as to obtain a group of weighted images (S12); and on the basis of the group of weighted images, which are obtained by means of reconstruction, performing fitting to obtain a parameter value (S13). In this way, by means of the gradient-domain matrix elastic network infimal convolution regularization accelerated magnetic resonance parameter imaging method, a gradient-domain elastic network infimal convolution regularization model is designed, such that the parameter imaging acceleration rate is improved while ensuring the solving stability and precision of an inverse problem solution.
