MRI compatible headset

摘要

A wireless headset capable of receiving audio signals transmitted wirelessly and compatible for use in an MRI scanner is disclosed. The headset includes a first wireless module connected to the first earphone and a second wireless module connected to the second earphone. Each wireless module is electrically connected to a speaker in the respective earphone. The first wireless module receives the audio signal from a remote source and coordinates transmission of the audio signal to each of the speakers. The compact nature of each earphone minimizes the length of wire runs. In addition, the headset is made of materials having low magnetic susceptibility such that they will not be affected by the magnetic field from the MRI scanner.

主权项

1. A headset for a patient to wirelessly receive an audio signal during a magnetic resonance image (MRI) scan, the headset comprising:
a first earphone operable to be worn by the patient within an MRI scanner during the MRI scan, the first earphone including:
a first housing having at least one opening through a surface located proximate to a first ear canal of the patient when the first earphone is worn by the patient,a first radio frequency (RF) audio module mounted proximate to the first housing such that the first RF audio module is located within the MRI scanner during the MRI scan, the first RF audio module configured to receive the audio signal and to wirelessly retransmit at least a portion of the audio signal, anda first speaker mounted within the first housing and proximate the at least one opening of the first housing, electrically connected to the first RF audio module, and configured to reproduce at least a portion of the audio signal; a second earphone operable to be worn by the patient within the MRI scanner during the MRI scan, the second earphone including:
a second housing having at least one opening through a surface located proximate to a second ear canal of the patient when the second earphone is worn by the patient,a second RF audio module mounted proximate to the second housing such that the second RF audio module is located within the MRI scanner during the MRI scan, the second RF audio module configured to receive the portion of the audio signal retransmitted from the first wireless audio module, anda second speaker mounted within the second housing and proximate the at least one opening of the second housing, electrically connected to the second RF audio module, and configured to reproduce the portion of the audio signal received by the second RF audio module; and a headband having a first end and a second end, wherein the first earphone is connected proximate to the first end and the second earphone is connected proximate to the second end.
