  • Patent number: 10317501
    Abstract: Systems and methods for magnetic resonance fingerprinting (“MRF”) using highly differentiated trajectories that optimize differentiation between magnetic resonance signal patterns as a function of relaxation time(s) and static magnetic field homogeneity are described. Using the optimized acquisition parameters, MRF can be performed in the presence of inhomogeneous magnetic fields. Flip angle homogeneity can also be incorporated into the dictionary matching process to simultaneously estimate quantitative parameters of the subject and radio frequency coil transmission homogeneity profiles.

  • Patent number: 10274557
    Abstract: Embodiments of the present invention address the problems with previously known MRI enhancement resonators. The embodiments provide capacitances that are sufficiently large to result in resonance frequencies that are sufficiently low for medical MRI applications in devices that are sufficiently small for implantation into the body. Further, the capacitance and resonance frequency of the MRI enhancement resonator may be easily adjusted to particular desired values by selecting corresponding thin-film dielectrics, or thicknesses of such thin-film dielectrics. Moreover, the design and geometry of the embodiments provide MRI enhancement resonators with high Q-factors. The construction and material of such MRI enhancement resonators also yield flexible and biocompatible devices that are appropriate for applications involving implantation into the body.

  • Patent number: 10247800
    Abstract: A method uses an artificial neural network (ANN) to automatically produce a magnetic resonance (MR) pulse sequence. A first MR signal corresponding to a first tissue and a second MR signal corresponding to a second tissue are identified. An RF pulse to be applied to the first and second tissues is selected. Based on at least the first MR signal, the second MR signal, and the RF pulse, an updated first MR signal and an updated second MR signal are determined. A difference is computed between the updated first MR signal and the updated second MR signal. The difference is added to an accumulated difference. The RF pulse selecting, updated first and second MR signal determination, difference computation and adding are repeated. The ANN is controlled to use reinforcement learning to select the MR imaging pulse sequence based, at least in part, on the accumulated difference.
