Abstract:
1. A base station for an MRI compatible patient monitor device, the base station positionable outside a bore of a magnet during an MRI examination, the base station comprising: a movable stanchion disposed in a shielded magnetic resonance room; a monitor unit which receives wireless transmissions of data from a patient sensor that acquires physiological signals from a patient in the bore of the magnet, the monitor being mounted on the stanchion; and a display unit which wirelessly communicates with the monitor unit and displays information associated with the data received from the patient sensor by the monitor unit, the display unit being movable independently of the monitor unit in the shielded magnetic resonance room, the display init including: a rechargeable battery that provides power to the display unit when the display unit is remote from the stanchion, the stanchion providing charging current to the rechargeable battery when the display unit is mounted to the stanchion, and a magnetically hardened power supply operative, without saturation, in high-flux magnetic fields up to 15,000 Gauss to manage the rechargeable battery during an MRI examination.
