ECG and respiration gating are used to suppress imaging artifacts due to respiration and cardiac movements

ECG and respiration gating are used to suppress imaging artifacts due to respiration and cardiac movements. Both are important in cardiac and abdominal imaging for both 2D and 3D data sets.

Respiration Gating
The respiration gating is controlled using the respiration signal acquired by the system from the mouse/rat platform. The gating can be turned on/off from the Physiology panel.

ECG Gating
The ECG gating is controlled using the ECG signal acquired by the system from the mouse/rat platform. The gating can be turned on/off from the Physiology panel. The markers can be set anywhere in the cardiac cycle. Therefore the images can be gated to systole and/or diastole. It is possible to capture a 2D image of the heart in full systole and/or diastole.
Furthermore, ECG gating minimizes artifacts not only in cardiovascular applications but all types of imaging. Often, the respiration gating may not be enough to remove movement artifacts for anatomies close to the chest. Setting up the ECG gating along with the respiration gating will minimize the artifacts due to the heart movements as well.
