Description
A new version of the 1025T is now available. It is the Model 1025T-FOT where the temperature measurement is made using a robust fiber optic sensor rather than a thermistor temperature sensor. This new model offers several advantages including eliminating the possibility of wire artifacts in CT images. The 1025T with the thermistor temperature sensor is still available because thermistor temperature sensors are less expensive than fiber optic temperature sensors. The 1025T is configured at the factory for either fiber optic temperature or thermistor temperature.
The Model 1025T monitoring and gating system was designed to meet the physiological monitoring and gating needs for anesthetized mice, rats and larger animals in the laboratory, PET, CT, SPECT, Optical and some MR environments. The system consists of an ECG, respiration and temperature data acquisition and processing module located near the animal which is connected to a PC located near the operator console. The PC displays multiple waveforms, measured values, trends and gating pulses. The data Acquisition module is controlled by menu driven software from the PC. The following options are available for use with the 1025T: pulse oximetry, capnography, invasive blood pressure, fiber optic temperature, fiber optic minimally invasive pressure.

| The animal’s electrocardiograph (ECG) waveform is measured using three leads with sub-dermal needle electrodes, gold disk surface electrodes or radio translucent pads. The waveform is processed to detect R-waves and determine the heart rate. Temperature is measured using a small rectal temperature probe. The 1025T can be factory configured with either a thermistor or a fiber optic temperature sensor. The temperature measurement can be used in conjunction with a Heater System to regulate the temperature of the animal. Both air and fluid heater systems are available. Temperature variations of ±0.2 oC can typically be obtained. A respiration waveform is measured using a small pneumatic pillow placed next to the animal’s abdomen. The waveform is automatically processed to detect inspiration, expiration and respiration rate. Optional modules can be used with the 1025T to provide pulse oximetry, capnography, invasive blood pressure, fiber optic temperature, minimally invasive pressure. Auxiliary TTL input channels allow the user to gate from user generated pulses. Optionally, auxiliary analogue input channels allow the user to acquire, record, display and gate from user generated waveforms. A sophisticated user configured gating algorithm allows gates generated from each measured waveform to be combined to supply a trigger to the imager. The user can control the start, stop and width of each gate. Power is supplied from an external 12 VDC power supply which operates from 100-230 VAC, 50-60 Hz. |
