A method is provided for processing a dual-energy CT scan image, which includes filtering the pixels in a dual-energy CT scan image to obtain pixels to be grouped; grouping the pixels to be grouped into a plurality of pixel groups based on the positions of the pixels to be grouped in the dual-energy CT scan image; performing material decomposition on the pixels in each pixel group; and determining the object corresponding to each pixel group based on the results of material decomposition. By using the method, the scan time and the X-ray dose radiated to a target (e.g., a user to be diagnosed) are reduced.

The present invention provides a method for accessing a wireless network, so as to implement acquisition of system synchronization during the process of accessing the wireless network in the situation that a physical frame structure can be configured dynamically. The method for acquiring system synchronization comprises: searching a physical frame on a current sub-channel; resolving a system information channel (SICH) and a control channel (CCH) in the found physical frame, wherein the SICH indicates a structure of the physical frame, and the CCH indicates allocation of system resources; and acquiring a system parameter from the physical frame by using the resolving result. A device for implementing the above method is further provided.

In the present invention, before data transmission, a 'connection', between a requesting end and a destination end, identified by a traffic flow identifier (FID) is established or modified through traffic flow management. Therefore, when the requesting end and the destination end perform data transmission on the traffic flow, the FID alone can sufficiently serve as the identifier, so as to save the need of carrying the destination end identifier in each exchanged data packet, thereby simplifying the operation.
