Abstract:
A magnetic resonance signal receiving apparatus comprising:a plurality of receiver coil units disposed with respect to each other to define a phase array, each unit of said plurality of receiver coils defining a loop; a plurality of capacitors each provided in series in each loop of each unit of said plurality of receiver coils; a plurality of first diodes; a plurality of inductors each connected in parallel to each of said plurality of capacitors in each said loop through a pair of said plurality of first diodes connected in parallel in opposing polarity to each other; a plurality of second diodes each provided in series in said loop of each unit of said plurality of receiver coils; and means for enabling selective ones of said units of said plurality of receiver coils and for disabling others of said units of said plurality of receiver coils by independently and selectively controlling bias of said plurality of said second diodes provided in said loop of each unit of said plurality of receiver coils so that signals received by said units of said plurality of receiver coils are selectively controlled in desired combinations to thereby simplify signal receipt, said means being connected to each unit of said plurality of receiver coils and to each of said plurality of second diodes connected in said loop thereof.
