SYSTEMS AND METHODS FOR IMAGE RECONSTRUCTION IN MAGNETIC RESONANCE IMAGING
Some embodiments of the present disclosure disclose systems and methods for robust magnetic resonance image reconstruction that can model for all or nearly all components in the magnetic resonance imaging system, that possess compressibility features to speed up reconstructions, and that can be optimized such that the reconstruction can be performed within a short period of time.
1 . A method of magnetic resonance imaging (MRI), comprising:
applying, using a transmit coil and a radio frequency (RF) source, a total magnetic field including magnetic field gradients and one or more RF pulse sequences, respectively, to measure one or more states of a sample;
receiving, from one or more receive coils, MRI measurement data acquired by the receive coils during an acquisition window, the MRI measurement data including magnetic resonance signal data emitted by the sample;
linearly combining, via a processor, a subset of the MRI measurement data to generate a first encoding matrix, the first encoding matrix being a sub-matrix of a second encoding matrix configured to (i) be generated by linearly combining all the MRI measurement data, and (ii) represent the one or more states of the sample, the transmit coil and the receive coils and; and
determining, by the processor, a characteristic of the MRI measurement data based on a computation of the first encoding matrix.
