A method and apparatus for producing an image from an extended volume of interest using a Magnetic Resonance Imaging (MRI) system are provided. The apparatus comprises a magnet assembly, a gradient coil assembly, at least one radiofrequency coil, a positioning device for translating the volume using along an axis of the MRI system and a plurality of receivers. A plurality of MR signals are detected from the radiofrequency (RF) coil, as the positioning device is translated, and are sent to the plurality of receivers. Each of the receivers are configured to be adjusted in either phase or frequency in response to the positioning device being translated. A plurality of respective sub-images are computed corresponding to the plurality of MR signals for each of the receivers and for the given field-of-view (FOV) at each of the incremented positions. A composite image of the volume of interest is formed by combining the respective sub-images.
