发明名称 SAR REDUCTION IN MR IMAGING WITH PARALLEL RF TRANSMISSION
摘要 A computer readable storage medium in an example has a computer program stored thereon and represents a set of instructions that when executed by a computer during MR imaging causes the computer to: acquire a B1 field map for each transmit coil of a parallel RF transmit coil array; determine with a computational algorithm an excitation pulse scheme for a target excitation profile based on at least one effective B1 field map for a plurality of transmit coils of the parallel RF transmit coil array; and generate at least one SAR-reduced RF pulsing sequence for a respective transmit coil of the plurality of transmit coils of the parallel RF transmit coil array. The parallel RF transmit coil array is capable of having any parallel RF transmit coil array geometry. Each effective B1 field map reflects inductive coupling effects present between a transmit coil and at least another transmit coil.
