摘要： A method and system for receiving magnetic resonance signals, and a magnetic resonance imaging system are provided. The method includes dividing coil units in a receiving coil array into different coil unit groups. For each of the coil unit groups, correlations are established between carrier frequencies and the signals received by each coil unit in the coil unit group. Low noise amplification is performed, and filtering and frequency mixing is performed on the signals received by all the coil units in the coil unit group according to the correlations to obtain intermediate frequency signals borne on the respectively corresponding carrier frequencies of an identical channel. After performing amplification and filtering on the intermediate frequency signals, the intermediate frequency signals are output to an analog-to-digital conversion unit to perform digital sampling so as to obtain digital domain signals.

The RF coil device includes multiple coil segments and a multi-selection switch. Input terminals of the multi-selection switch are each connected to a different coil segment. An output terminal of the multi-selection switch leads to an RF output channel.

Multiple coil segments connected to the input terminals are not in consecutive positions, and the number of coil segments by which any two of the multiple coil segments are spaced apart is no fewer than the maximum number of coil segments required for one MRI imaging less 1. The MRI apparatus includes the RF coil device.

摘要： A Forwarding Information Base (FIB) caching system and scheme that selects and generates a minimal number of non-overlapping prefixes for the FIB cache to improve computer-based network communications and operations efficiency, accuracy and speed. Because the cached prefixes do not cover any longer prefixes in the full FIB, the present invention thus avoids cache-hiding issues. The system further comprises a FIB caching updating component that systematically handles cache misses, cache replacement, and routing updates.
