  • Patent number: 11923127
    Abstract: The present disclosure relates to a tank of a high-voltage generator including a tank body and a tank lid. There is an opening in the tank lid. The opening is connected to the bellows so as to counteract the volume change of the transformer oil and avoid generation of bubbles. The tank includes a positive transformer, a negative transformer, a bellows, and other components. The high-voltage winding is embedded in the PCBs. The outer insulating bushing is covered by the PCBs so as to improve the insulativity between the turns of the high-voltage winding. In addition, oil barriers may be placed between the positive and the negative transformers, or between the transformers and the ground so as to eliminate the bridge breakdown effect and make the electric field uniform. By means of said measures, the present disclosure improves the stability of the high-voltage generator.

  • Publication number: 20220322958
    Abstract: A magnetic resonance (MR) apparatus is provided. The MR apparatus may include at least one processor. The at least one processor may be configured to obtain an operating state of the MR apparatus; and select, from two or more power supply devices, a power supply device for supplying power for at least one coil of the MR apparatus according to the operating state of the MR apparatus. The at least one processor may be configured to obtain, through a relay component connected to a coil section, motion information of at least one component of the coil section; and generate, based on the motion information, control instructions for adjusting communication parameters of a first directional communication module of the coil section and a second directional communication module of the relay component.
