摘要： In a temperature control method for magnetic field components of a permanent magnet arrangement of a magnetic resonance system, temperature stability of the magnetic field components is achieved by maintaining the temperature of the two sides of the magnetic field components constant, with a difference being maintained between the temperatures of the two sides of the magnetic field components so that a temperature gradient is formed within the magnetic field components. Once the temperature gradient is formed, dynamic temperature stability is established within the magnetic field component. When this dynamic temperature stability is broken by thermal disturbance, the temperature gradient allows the thermal disturbance to be quickly transmitted to the lower magnetic yoke and is further transmitted to the outside through the base of the magnetic resonance system so that the thermal disturbance is smoothed and dynamic temperature stability is reestablished.

摘要： The invention relates to a method of forwarding multicast message in network communication. In the method: first, establish forwarding match condition at the ingress interface of the network device required to forward multicast message, the forwarding match condition specifies forwarding rule for the multicast message; then, compare the multicast message to be forwarded to network device through the interface with the forwarding match condition, and forward the multicast message according to the comparing result. The invention can configure the sending mode of messages according to requirement and can effectively avoid risks in security that may be caused by the broadcast mode for the multicast messages in the link layer as well as efficiency loss caused by receiving a great deal of invalid multicast messages, and the configuration is simple, and more convenient use and management is realized. In the present invention, forwarding multicast message according to an established multicast message forwarding rule greatly reduces the number of various multicast protocol messages generated in the multicast network and saves bandwidth resource of network.

摘要： The present invention concerns a method and an apparatus for phase-calibrating an MRI pulse sequence which is used to calculate a linear phase and a constant phase to perform phase calibration on the scanned data, wherein a corresponding pre-scan without a phase encoding gradient is performed before a diagnostic scan. A reference echo is selected from the echoes obtained in the pre-scan. On the basis of the reference echo the constant phase is calculated to be used in performing the phase calibration in the scan. The constant phase that is obtained is correct and not affected by phase jumping. A further image reconstruction performed on the phase-calibrated data produces clear and artifact-free images.
