Biopac OXY-MRI SpO2 Module with Sensor for Human MRI

Biopac OXY-MRI SpO2 Module with Sensor for Human MRI

OXY-MRI is a stand-alone system for adult human pulse oximetry (SpO2) in the MRI; it can also be used with a BIOPAC MP150 or MP100 Research System.

The system includes an SpO2 amplifier and a fiber-optic oximetry sensor for the finger, plus a signal isolation adapter INISO and interface cables to connect to an existing HLT100C for MP Research Systems. Additional finger sensors are available as OXY-MRI-SENSOR.

The SpO2 amplifier is used in the MRI control room, the 9 m fiber-optic sensor cable is passed through the wave guide, and the finger sensor is attached to the subject in the MRI chamber room. MRI-compatibility rated to 3.0 Tesla.

*OXY-MRI is not intended for animal use*
