In a method and system for processing radio frequency signals of a tubular surface coil, the N channels of coil output signals are generated based on M channels of radio frequency signals acquired by M coil units in the tubular surface coil, wherein N is an even number greater than 1 and is less than or equal to M, and the N channels of coil output signals can be divided into N/2 pairs, with the two channels of coil output signals in each of the pairs respectively coming from the coil units located at symmetrical positions of the tubular surface coil. The respective modulus values of the two channels of coil output signals in said each pair of coil output signals are multiplied to obtain N/2 products which are then summed, and the square root of the summed result is computed, so as to generate a lateral cross-sectional image according to the computed result of square root. The signal strength in an imaging area and the uniformity of signal to noise ratio are thereby improved.
