  • Publication number: 20220092777
    Abstract: The disclosure belongs to the technical field of radiomics, and particularly relates to an extraction method for radiomics feature information of knee joint effusion. each layer of an image is segmented into a plurality of regions, the interference of image noises in each region is removed, then whether each region after interference removal is an effusion region or not is judged, finally, the radiomics features of each effusion region are calculated, interpolation processing is respectively implemented on the obtained image position and the area of the effusion regions, an effusion area simulation change curve is drawn, curve integration is implemented to obtain volume information, and all the extracted information is stored in a cell array of a MATLAB. thus the effusion information in the MRI image of the knee joint is automatically extracted, and meanwhile, the method is fast in speed, high in accuracy, good in repeatability.

  • Patent number: 7958220
    Abstract: An apparatus, method and system for acquiring IPV6 address is described. The apparatus includes a request module (101) and an allocation module (102), the request module (101) is adapted to send an IPV6 address allocation request to the allocation module (102), and acquire an allocated IPV6 address from an IPV6 address allocation acknowledgement returned from the allocation module (102); the allocation module (102) is adapted to allocate an IPV6 address according to the IPV6 address allocation request, make the allocated IPV6 address to be carried in the IPV6 address allocation acknowledgement, and return the IPV6 address allocation acknowledgement to the request module (101). The system includes a user terminal and an IPV6 address management device. The apparatus, method and system improve the security of IPV6 address in use while ensure the uniqueness of IPV6 address.
