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.
