| 摘要 |
The invention relates to a virtual coil emulation method to be used in a magnetic resonance imaging scan for acquiring a magnetic resonance image of an object (10), wherein the scan is performed by an MR system (1) using a physical coil arrangement (9; 11; 12; 13) comprising set of individual transmit coils, the coils being adapted for transmission of a desired RF transmit field to the object (10) for magnetic resonance spin excitation of the object (10), wherein each coil is associated with a physical transmit channel, wherein the RF transmit field corresponds to a virtual arrangement of two or more of said coils, wherein virtual transmit channel properties comprising virtual transmit channel weights are assigned to the RF transmit field, said virtual transmit channel weights describing the virtual complex RF field amplitudes with respect to each individual coil of the virtual coil arrangement required to be applied to the physical coils (9; 11; 12; 13) for generating the RF transmit field. |
