Abstract
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.
