Abstract:
1. An entertainment system for use with by a patient in a magnetic resonance imaging (MRI) device comprising: a. an audio component for producing audible sound waves from an electrical signal; b. a video component for producing a video image from an electrical signal; c. a control unit configured to generate the electrical signal for driving the audio component, the video component, or both, the control unit including: d. one or more cables extending from the control unit and battery to the audio component and the video component for electronic communication and providing power therebetween, the one or more cables including a shielding layer to reduce or prevent RF signals from entering, being emitted from, or both the one or more cables; wherein the system includes less than about 20 grams by weight of ferromagnetic material per Tesla of the MRI; wherein the shielding layers comprise about 2 to about 5 layers of conductive metal mesh which includes a network of elongated wires that define a plurality of openings therethrough having between 15 and 200 wires per inch; and wherein the control unit may be disposed within a magnetic bore of the MRI device during the operation thereof; wherein the cable allows control unit and battery to be placed outside the MRI imaging area during operation thereof to reduce MRI imaging anomalies.
