MAGNETIC RESONANCE TOMOGRAPH WITH ACTIVE INTERFERENCE SUPPRESSION AND METHOD FOR SUPPRESSING INTERFERENCE IN A MAGNETIC RESONANCE TOMOGRAPH

摘要

The invention relates to a magnetic resonance tomograph and a method for operating the magnetic resonance tomograph. The magnetic resonance tomograph has a first receiving antenna for receiving a magnetic resonance signal from a patient (100) in a patient tunnel, a second receiving antenna for receiving a signal having the Larmor frequency of the magnetic resonance signal, and a receiver. The second receiving antenna is located outside or near an opening of the patient's tunnel. The receiver is in signal communication with the first receiving antenna and the second receiving antenna, and is configured to suppress a noise signal received by the second receiving antenna in a magnetic resonance signal received from the first receiving antenna.
