The ECG & respiration gating system (GS4010) is intended to eliminate motion variability in rapid imaging system like ultrasound or optical imaging. This device can be used on small animals, such as mice, rats, guinea pigs and marmosets.

Accurate quantification in ultrasound often depends not only on having a great B-mode image but also on limiting movement within the field of view. ECG and respiration gating can pause the image at one specific time within the cardiac cycle and/or only acquire data when the animal is not actively breathing.

The system includes a 3.2 inch touch screen with signal display in a compact handheld format. The intuitive user interface is easy to use and modification of parameters is straightforward. 2 different visual feedback are available to the user: LED and signal display.
