Model 1025 Monitoring & Gating System

SA Instruments no longer offers for sale the MR-Compatible Model 1025 Monitoring and Gating System.  In 2011 the Model 1025 was replace with the Model 1030 MR-compatible Monitoring and Gating System. The Model 1030 offers improved performance at lower cost.  However we continue to offer service for the hundreds of Model 1025 systems that remain in service worldwide.  In addition all of SA Instruments MR-compatible options have been and will continue to be offered for use with the Model 1025.

When the Model 1025 was released in 2004 it was designed specifically to meet the physiological monitoring and gating needs for anesthetized mice and rats in the MR environment. The system consists of data acquisition modules located near the animal in the magnet bore and a control/gating module connected to a PC located near the operator console.

The PC displays multiple waveforms, measured values, trends and gating pulses. The data Acquisition modules are controlled by menu driven software from the PC.

Data acquisition modules are available to measure the following parameters:  ECG, respiration (three ways), temperature (two ways), pressure including invasive blood pressure (two ways), oxygen saturation and end-tidal CO2.

Waveform and Trend Data Acquistion

The ECG/Temperature Module resides in the magnet bore near the animal.  It measures temperature with a small rectal probe, ECG using two subdurmel or surface electrodes and respiration by coupling one of the ECG leads to the animal's abdomen.  Power is supplied by an external, rechargeable battery.  ECG, temperature and respiration measurements are amplified, digitized and transmitted out the magnet bore on an optical fiber cable to the Control/Gating Module.
The Respiration/IBP Module resides just outside the magnet bore, but close to the animal. It measures respiration using a small pneumatic pillow and blood pressure using a pressure transducer connected with tubing to an invasive line in the animal. Spare input channels allow event markers or auxiliary data to be acquired with the measured data. Power is supplied from either an internal rechargeable battery or an external power supply.

Measured data is digitized and transmitted outside the magnet room to the Control/Gating Module using optical fibers. The module sends data to the PC for display and receives instructions from the PC to control measurement and gating functions.  ECG and/or respiratory gates are generated by the Control/Gating Module's microprocessor and sent to the MR system. The delay from the R-wave peak to the MR system gate is user selectable as is the expiration gate delay and width. An optical output corresponding to the difference between the measured temperature and a user defined set point is available for controlling a heater.
