A patient monitoring system detects physiological signals from a patient during an MRI examination. The patient monitoring system wirelessly transmits data associated with the physiological signals to a remote base unit. The wireless transmission of data is carried out in a manner to not be disruptive to the MRI examination. The patient monitoring system has a removable, MRI magnet compatible battery.

Battery system for MRI compatible wireless patient monitor

A base unit operable with a wireless patient monitoring unit used to acquire physiological data during an MRI examination is constructed to have a detachable display unit. The detachable display unit wirelessly communicates with the base unit when in a roving mode. The detachable display unit may also have a magnetically-hardened power supply that does not saturate during an MRI examination. Such a magnetically-hardened power supply allows the display unit to operate when proximate or in the magnetic field generated by an MRI machine during an MRI examination.

A wireless patient monitor for MRI provides for on-board filtering of physiological signals from the patient to provide improved assessment and processing of MRI noise before the signal is affected by the transmission process. A system of powering of a wireless patient monitor using capacitors is also provided.

Wireless patient parameter sensors for use in MRI

A circuit for isolating line voltage from a patient in an MRI environment, uses a filter network tuned to line voltage and incorporating blocking capacitors to eliminate the need for bulky air core transformers, complex energy transfer systems, and ferromagnetic components, while providing reduced heating such as might produce patient discomfort.
