Abstract

A method and system for real-time reduction of noise during MRI data acquisition is disclosed. At least one antenna is placed in proximity to, or within the cavity of, a standard MRI apparatus, and in connection with a standard data acquisition setup. The data acquisition by the antenna is synchronized to the MRI pulses. Any residual signal is defined as noise; if a particular data subset is deemed to be noisy, the noise can be reduced or eliminated by, for example, remeasuring the data subset or by direct subtraction of the noise from the measured signal. By placing one antenna within and one in proximity to the MRI apparatus, the system and method can also be used to determine the actual level of RF shielding in the MRI apparatus.
