Abstract: Systems and methods for interference signal collection and processing are provided. The systems may obtain initial signals and first interference signals collected in at least one first time window during an MR scan of a target subject. The nuclei in the target subject may be in an excited state in the at least one first time window. The initial signals may be collected by a receiving coil of an MRI device, and the first interference signals may be collected by an interference signal acquisition device. The systems may also determine second interference signals collected by the receiving coil in the at least one first time window based on the first interference signals. The systems may further determine imaging signals collected by the receiving coil in the at least one first time window by correcting the initial signals based on the second interference signals.

Abstract: A transfer device and use thereof, and a glass bending forming system are provided. The transfer device includes a suction table. The suction table has a first edge-region and a second edge-region. The first edge-region surrounds the second edge-region. The suction table defines a first suction groove, multiple first suction holes, a first suction channel, and a second suction channel. The first suction groove is defined in the first edge-region. The multiple first suction holes are defined in the second edge-region. The first suction channel is in communication with the first suction groove and is used for providing a first negative pressure. The second suction channel is in communication with the multiple first suction holes and is used for providing a second negative pressure. The first negative pressure and the second negative pressure are used for sucking at least one glass sheet on the transfer device.

Abstract: A system and method for MRI are provided. a plurality of RF parameters for an MRI scan, using an MRI scanner, of a subject may be obtained. A first power loss and a first current square factor of the RF coil assembly under an unloaded condition of the MRI scanner may be determined based on the plurality of RF parameters. A total power loss of the MRI scan and a second current square factor of the RF coil assembly during the MRI scan may be determined based on the plurality of RF parameters. A second power loss of the RF coil assembly during the MRI scan may be determined based on the first power loss, the first current square factor, and the second current square factor. A SAR of the subject during the MRI scan may be determined based on the total power loss and the second power loss.
