  • Publication number: 20220374675
    Abstract: A three-dimensional track planning method based on improved particle swarm optimization algorithm is disclosed. During the process of searching an optimal three-dimensional track in a track space, Different inertia weights are set in different particle swarm iterative evolution stages. A maximum inertia weight is used to make global convergence in a set early stage of evolution, and a minimum inertia weight is used to make local convergence in a set late stage of evolution. Disturbance mutation operation in a motion process of particles is added based on swarm diversity. Infeasible particles are selected based on constraints. Constraint violation functions of infeasible particles are compared, and infeasible particles with small constraint violation functions are kept.

  • Publication number: 20220357415
    Abstract: Magnetic resonance images with improved image quality consistent with those obtained using parallel radio frequency (“RF”) transmission (“pTx”) techniques are generated from data acquired using single transmission hardware (e.g., single channel RF transmission). A deep-learning framework is used to train a deep neural network to convert images obtained with single transmission into pTx-like images. The pTx-like images have reduced signal variations and dropouts that may otherwise be attributable to B1+ inhomogeneities.
