Active decoupling of transmitters in MRI
Abstract:
A magnetic resonance imaging system includes a coupling compensation processor (70) for compensating induced magnetic coupling between n individual coil segments (38) of a coil arrangement (36). An adjusted signal determining device (74) determines an adjusted input signal for each of the n individual coil segments of the coil arrangement (36). A transmitting system (54) creates RF pulses in accordance with the determined adjusted input signals and transmits the RF pulses to corresponding coil segments such that the transmitted RF pulses compensate for coupling between the coil segments (38) in the digital domain.
