摘要： A method and apparatus is disclosed to analogically combine MR signals from RF coils to form multiple sets of analogically combined MR signals, and then digitally combine the analogically combined sets of MR signals to provide a digitized signal set for image reconstruction. The analogical combining followed by the digital combining of acquired MR signals improves intrinsic SNR of the RF coils used for data acquisition from a field-of-view (FOV) without compromising FOV for simultaneous MR data acquisition.
