A 2.4 GHz MRI compatible Bluetooth transceiver was constructed for use with a mouse and keyboard inside of a MRI room. Shielding and filtering prevented noise from Bluetooth electronics from entering the room. Only a few required small ferromagnetic parts were incorporated into the design. No noise was generated from the system. This was verified visually with phantom scan, a frequency spectrum obtained with a network analyzer, quantitatively with RF noise checks, and through technical specification from the manufacturer, FCC, and ETSI.
