摘要： An apparatus and method for reducing stray magnetic fields include a decoupling circuit includes a balun that comprises a transmission line. The transmission line includes a first spiral positioned substantially parallel to a first plane, the first spiral emanating from a inner portion of the first spiral in a first spiral direction. The transmission line also includes a second spiral positioned substantially parallel to the first plane, the second spiral emanating from a inner portion of the second spiral in the first spiral direction, wherein the inner portion of the first spiral is electrically coupled to the inner portion of the second spiral, and wherein the transmission line comprises a signal line and a ground line. The balun further comprises a first capacitor electrically coupled to the transmission line.

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.
