For continued patient safety and image integrity, use only those Invivo Research accessories
and equipment specifically designated for MRI.
SECTION 1
INTRODUCTION
1. INTRODUCTION
The Magnitude
T M
3150M MRI Monitor is an evolution of the Omni-Trak
T M
3150 MRI Monitor .
Among other features, the Magnitude
T M
3150M MRI Monitor includes Digital Signal Processing
(DSP) and an MRI View Mode. DSP provides improved ECG performance and reduction of MRI
gradient artifact. The MRI View Mode provides adaptive ECG gradient filtering techniques for
enhanced ECG display during MRI sequences. Both models of the 3150 MRI Monitor provide the
operator with ECG, Respiration, SpO2, NIBP, EtCO2 and Invasive Pressures monitoring. Full control
of patient monitoring is provided via the Invivo Research, Inc.
Millennia
®
3155A/3155MVS Monitor
equipped with MRI shielding and set to Remote Communication Mode.
If operating a dual monitor system, the 3155MVS and 3155A patient monitors are interactive with one
another through the 3150/3150M. As the “communication unit” the 3150/3150M acts to keep the
commands that control patient parameter function synchronized throughout the MRI monitoring system.
Should the 3150/3150M be turned off, it is possible to have patient parameters on the 3155A set to a
particular configuration with the 3155MVS set to a different configuration; when the 3150/3150M is
turned on the system will synchronize and all patient configurations will reflect the 3155A
configuration.
This Operations Manual will describe both the
Magnitude
TM
3150M
and
Omni-Trak
TM
3150 MRI
Monitors
in detail. For simplicity the manual will refer to both these systems by the name “
3150(M)
MRI Monitor ” except in the cases where a feature applies only to one of the two systems, in which
case the specific 3150(M) MRI system will be referenced. Also, in the case of the Millennia
®
3155MVS
and 3155A Remote Monitors, they will be referred to (in this manual) only as “Remote Monitor(s).”
1.1 Features.
The
3150(M) MRI Monitor
has been carefully engineered to take full advantage of the most
advanced technology.
!
Integrated Control. Every feature of the 3150(M) MRI Monitor is synchronized with the Remote
Monitor. This removes the need to manually check each monitor before beginning a scan.
!
Software Control. The integration of the 3150(M) MRI Monitor and the Remote Monitor into a
cohesive
MRI Monitoring System
is controlled by advanced software.
!
Alarms and Trending. The 3150(M) MRI Monitor sends patient information to the Remote
Monitor, where it can be analyzed and stored. Setting of Alarm High and Low Limits, Alarm
Latching/Non-Latching, Alarm Tone and Volume, as well as all Trend Information Storage, is
performed at the Remote Monitor.
!
Complete Parameter Monitoring. This monitor will provide accurate and up-to-the-minute
monitoring of a patient's ECG, NIBP, Invasive Blood Pressure, SpO2 and ETCO2.
!
Digital Signal Processing (Magnitude
TM
3150M MRI Monitor only). Digital Signal Processing
(DSP) of the ECG waveform is an innovative approach in removal of MRI gradient interference
artifact from the ECG waveform.
