Abstract:
When subjecting a patient to an MRI scan, noise generated by gradient coils in an MRI device is beautified by playing a complementary musical piece that matches the gradient coil noise in one or both of tempo and musical key. Complementary musical pieces (e.g., songs, tunes, melodies, etc.) are pre-generated for specific gradient coil sequences. Upon selection of one or more sequences to be executed during an MR scan, complementary musical pieces for the selected sequence(s) are identified and played back to a patient in the bore of the MRI device during the scan to alleviate patient stress. Tempo and/or musical key of the complementary musical pieces is adjustable (a priori or in real time) to synchronize the complementary musical piece(s) to a specific gradient sequence both rhythmically and harmonically.
