Claim:
1. A method for operating a magnetic resonance imaging (MRI) device for habituating a patient and/or user to acoustic-noise of said device's operation; said device having: a main-magnet which generates a basic magnetic-field; radio-frequency (RF) coils, used for transmitting and receiving RF-signals from a patient; a gradient system containing: slice-selection, phase-encoding and frequency-encoding gradient-coils, for localizing said RF-signals; and a control-unit for supplying respective currents to said gradient-coils and said RF-coils to produce pulse-sequences; said method comprising steps of: a. listing a required set of said pulse-sequences (RSPS) for said patient; b. determining acoustic-noise of each of said RSPS; c. reordering said RSPS to an ordered required set of said pulse-sequences (ORSPS); and d. operating, by means of generating said pulse-sequences, according to said ORSPS; wherein said step of reordering of said RSPS is according to a predetermined scale of acoustic-noise of said pulse-sequences; thereby habituating said patient and/or user to said acoustic-noise, and wherein said scale of acoustic-noise comprises a time-function with a positive time-derivative.
