    Abstract: In a method and apparatus for magnetic resonance imaging, in order to enable improved saturation of magnetic resonance signals during an acquisition sequence, the acquisition sequence includes a readout block set with multiple readout blocks, a readout saturation pulse set with multiple readout saturation pulses, and an intermediate saturation pulse set with one or more intermediate saturation pulses, wherein the readout saturation pulse set is disjoint from the intermediate saturation pulse set, at least one readout block of the readout block set includes a readout saturation pulse of the readout saturation pulse set, and at least one intermediate saturation pulse of the intermediate saturation pulse set takes place between two successive readout blocks of the readout block set.

    Abstract: A catch device and a shell liner for a medical imaging apparatus and a magnetic resonance imaging (MRI) apparatus that has an elastic arm, the elastic arm having a clamping portion, two bending portions located on two sides of the clamping portion and two end portions formed by extension of the ends of the two bending portions away from the clamping portion, the two end portions being used for being fixed to a liner of the first shell; and at least one roller, the roller being rotatably sheathed on the clamping portion of the elastic arm and clamping an edge of the second shell to the liner of the first shell by using an elastic force of the elastic arm, and an axial direction of the roller is parallel to the liner of the first shell and the edge of the second shell. The catch device achieves a simple and firm connection between apparatus shells, and meets requirements for a pleasing appearance and convenient application and maintenance.

    Abstract: A magnetic resonance imaging (MRI) method and apparatus in which conductors are installed in the space between a static coil unit and a gradient coil unit to eliminate asymmetry of eddy current induced in the static coil unit. The structure permits a symmetrical distribution of eddy current when the concentric arrangement of the static coil unit and gradient coil unit has deviated. The MRI apparatus includes: a static coil unit configured to form a static field in a subject; a gradient coil unit configured to form a gradient field in the static field; and one or more conductors installed in the space between the static coil unit and the gradient coil unit, and configured to symmetrically distribute eddy current induced in the static coil unit.
