Systems, methods and devices are configured for integrated parallel reception, excitation, and shimming (iPRES). Parallel transmit/receive (which can include Bshimming and/or parallel imaging capabilities) and Bshimming employ the same set of localized coils or transverse electromagnetic (TEM) coil elements, with each coil or TEM element working in both an RF mode (for transmit/receive and Bshimming) and a direct current (DC) mode (for Bshimming) simultaneously. Both an RF and a DC current can flow in the same coil simultaneously but independently with no electromagnetic interference between the two modes. This invention is not only applicable when the same coil array is used for parallel transmit, receive and shim, but also when two separate coil arrays are used. In that case, the Bshimming capability can be integrated into one of the coil arrays (i.e. a transmit array with Bshimming capability or a receive array), thereby increasing the flexibility and practical utility of the iPRES technology.

Circuits for magnetic resonance imaging systems for integrated parallel reception, excitation, and shimming

Magnetic resonance imaging systems for integrated parallel reception, excitation and shimming and related methods and devices

MRI systems with a new concept and hardware modality configured for parallel transmit, receive, and shim to address Band Binhomogeneity, both of which increase with field strength. This invention benefits from a number of advantages over existing technologies: it can save valuable space within the MRI magnet bore, largely reduce the manufacturing cost of MRI scanners, and avoid the electromagnetic interference issue associated with existing technologies.
