摘要:
The invention relates to a magnetic resonance imaging apparatus including an array of two or more RF antennas for transmitting RF pulses to and receiving MR signals from a subject positioned in an examination volume, and where the RF antennas have spatial transmit and receive sensitivity profiles. The apparatus is configured to control the temporal succession, the phase, and the amplitude of the RF feeding of each individual RF antenna. The apparatus is also configured to determine the phases and amplitudes from the spatial transmit sensitivity profiles of the RF antennas, and reconstruct a MR image from a combination of the received MR signals received via the individual RF antennas and from the spatial receive sensitivity profiles of the RF antennas. Further, the apparatus is configured to determine the spatial transmit sensitivity profiles of the RF antennas from the spatial receive sensitivity profiles of the RF antennas, or vice versa.
