The new Model 1040 monitoring and gating system was designed specifically to meet the physiological monitoring and gating needs for anesthetized rodents in MPI scanners. The Model 1040 consists of a Respiration/Temperature data acquisition module located just outside the magnet near the animal 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 Model 1040 is MR and CT-compatible.
The Model 1040 Control/Gating Module sends and receives digitized data over two fiber optic cables to and from the Respiration/Temperature Module. It sends data to the PC for display and receives user instructions from the PC to control measurement and gating functions. Gates generated by the Control/Gating Module’s microprocessor are sent to the MPI system. Gate delay and width are user selectable.

The Control/Gating Module has the capability to control an air heating system which can regulate the temperature of animals undergoing MPI. The system has a MR-compatible Heater Module that is positioned near the magnet bore and a Fan Module located outside the magnet room.
Pulse oximetry can be added to provide heart rate, oxygen saturation, a cardiac waveform and cardiac gates. The Pulse Oximetry Module is positioned near the magnet with the Respiration/Temperature Module and uses a fiber optic sensor to monitor the rodent in the magnet.
