Respiratory Gating

Synthetic Trigger/Sync
By default, the "Synthetic Trigger" (Respiratory-trig-
gered scanning) or "Synthetic Sync" (Respiratory-gated
scanning) is activated for all predefined Respiratory
scan protocols. It is recommended to always keep it
activated for examinations with contrast medium.
In case of Respiratory signal loss during the acquisi-
tion, this will ensure the continuation of the triggered
scans or allows a Respiratory signal to be simulated for
retrospective gating. If it is deactivated, the scanning
will be aborted in case of Respiratory signal loss during
the acquisition.
