1. A magnetic resonance elastography system, comprising:
a magnetic resonance imaging device, comprising:
a scanner;
a patient receiving region surrounded at least partially by the scanner; and
a patient couch configured to move a patient into the patient receiving region;
a vibration applicator configured to be arranged on the patient for a magnetic resonance elastography examination; and
an elastography device that is separate from the vibration applicator, the elastography device comprising:
a driver;
a force transmitter configured to transmit a drive moment from the driver to the vibration applicator; and
an electromagnetic compatibility (EMC)-tight shield housing having a cylindrical radiofrequency (RF) hollow conductor,
wherein the driver is arranged within the RF hollow conductor, and
wherein the EMC-tight shield housing enables the elastography device to be disposed adjacent to the patient couch during the magnetic resonance elastography examination.
