SAII’s monitoring and gating systems are compatible with MR, CT, SPECT and PET imaging systems. Sensors measure ECG (electrocardiogram), respiration, temperature and blood pressure in sedated mice, rats and other small animals undergoing imaging research. We provide a continuous monitor of animal physiologic status while generating gate signals to synchronize scanner data acquisition with cardiac and respiratory motion. Our MR-compatible heater can control the temperature of a mouse or rat, under sedation, during Magnetic Resonance or other imaging procedures.
