Abstract: A superconducting magnet (10) generates a uniform, static magnetic field through a central bore (12) along its longitudinal or z-axis. An insertable coil assembly (40) is inserted into the bore with a radio frequency shield (76, 84) for providing a radio frequency shield between the insertable coil assembly and a surrounding, whole body radio frequency coil assembly (32) and a whole body gradient magnetic field coil assembly (30). The insertable coil includes a gradient coil (44a) including conductors (52) mounted on a dielectric former (50) with a dielectric constant below 4.0. The conductors are relatively narrow and spaced relatively far apart to minimize capacitive coupling with a closely adjacent insertable radio frequency coil (70a). Filters (60, 64) are connected with the conductors of the gradient coil to prevent the gradient coil conductors from supporting radio frequency signals while permitting ready support of kHz frequency currents. An RF filter (106) connected between the insertable gradient coil and an insertable gradient coil control (100) prevents induced radio frequency signals from being transmitted to the insertable gradient coil.

Abstract: Superconducting magnets (10) of a magnetic resonance imager create static magnetic fields through an examination region (12). Gradient magnetic field coils (30) under control of a gradient magnetic field control (42) generate gradient magnetic fields across the examination region (12), as a whole. A plurality of surface coils (36, 38) receive radio frequency signals from each of two distinct subregions within the examination region (12). The two receiver coils are connected with separate receivers (60.sub.1, 60.sub.2) which demodulate the received magnetic resonance signals. The magnetic resonance signals are reconstructed (76) into an image representation (80, 82) of the first and second subregions. In the embodiment of FIGS. 1 and 2, a radio frequency transmitter (40) and a whole body coil (32) generate and manipulate the magnetic resonance signals within the first and second subregions. In the embodiment of FIGS. 3 and 4, a plurality of transmitters (40.sub.1, 40.sub.2, . . . ) convey RF signals to the surface coils such that the surface coils operate in both a transmit and receive mode. Regardless whether a single transmitter or a series of transmitters is utilized, a sequence control (44) controls the transmitter(s) and the gradient control (42) to conduct conventional magnetic resonance imaging sequences in coordination in both subregions.
