SECTION 1
THEORY OF OPERATION
1.0 THEORY OF OPERATION
1.1 General Description. The Millennia
®
3155MVS/3155A Monitor is the Remote Control
Unit in the Invivo Research, Incorporated 3150 Series MRI Monitoring System. This monitor
provides Remote Control (through a cable or RF Radio Link) to a
Omni-Trak
TM
3150/Magnitude
TM
3150M MRI Patient Monitor (located in the MRI Magnet Room). Used with the Omni-Trak
TM
3150 MRI Patient Monitor , the Millennia
®
3155MVS/3155A Monitor provides four waveform
traces compiling, processing, analyzing and displaying patient data from up to seven different patient
parameters. The information that this Monitoring System is capable of supplying to the physician
may be used as an aid in the determination of a diagnosis concerning the condition of a patient.
There is no direct patient connection to the
Millennia
®
3155MVS/3155A Monitor (patient
connection is performed in the Magnet Room with the Omni-Trak
TM
3150/Magnitude
TM
3150M
MRI Patient Monitor
) except in the case of Agent monitoring when the Millennia
®
3155A is used
with the patient sample line connected directly into the front of the monitor. The
Millennia
®
3155MVS/3155A Monitor is compact, comes equipped with up to three batteries to supply
emergency and/or transport power plus may "float" between the Magnet Room and Control Room
(as determined by the needs of each unique monitoring situation). It also contains (as a optional
feature) a recorder designed to provide printouts of the concise charts and trends required by today's
specialists for analysis and documentation. The Millennia
®
3155MVS/3155A can be used inside the
MRI Magnet Room when positioned at or outside the 1000 Gauss (0.1T) Field Line. For the
purposes of this manual, the Omni-Trak
TM
3150 and Magnitude
TM
3150M MRI Patient Monitors will
be referred to as the 3150/3150M and the Millennia
®
3155A and 3155MVS Monitors will be referred
to as the 3155MVS/3155A.
During MRI procedures that require anesthetic agents monitoring, where the 3155A is used in the
MRI exam room, the dual monitor system (software MDC01 and higher) allows the operator to add
a 3155MVS to the MRI monitoring system. The 3155MVS and 3155A interact through the
3150/3150M to allow monitoring at a remote site (such as the MRI control room).
