Systems, devices and methods for performing a magnetic resonance imaging scan of a patient. For example, a method of performing a magnetic resonance imaging scan on a patient can include monitoring a physiological signal level of the patient, analyzing the monitored physiological signal level, and providing instructions to the patient and/or changing the environmental conditions exposed to the patient. The instructions and/or the change of the environmental conditions of the patient can be based on the monitored physiological signal level. The instructions can include an acoustic command and/or a visual command. The changing of the environmental conditions can include visual simulation, acoustic stimulation and/or air conditioning change.
