System for real time - noise suppression in the case of the mrt - data acquisition

摘要

A system for the determination of the shielding degree in a mrt - device and to the real time reduction of noise, which in an mrt - device during an mrt - data acquisition is generated, which a hf - pulse generating means for generating of hf - pulses for the mrt - data acquisition and a cavity, wherein said system comprises:at least one antenna at a location selected from the group consisting of (a) in the vicinity of said mrt - device and (b) within the cavity of the said mrt - device;a data acquisition means in communication with at least one antenna and in connection with said hf - pulse generating means; anda synchronization means for synchronizing the data acquisition by said data acquisition means with mrt - pulses that of said mrt - device are generated.
