Abstract: A method of operating a magnetic resonance imaging (MRI) device for habituating a patient and/or user to acoustic-noise of the device's operation. The method includes: listing a required set of the pulse-sequences (RSPS) for the patient, modifying the RSPS to a new set of sequences (NSPS) further comprising at least one demo-sequence, and operating, by means of generating the pulse-sequences, according to the NSPS.
