4 Align the PERU on the patient in the direction of the patient's feet.
5 For the special case of triggered flow measurements/flow
quantification in the head region, please position the PERU next to
the patient's head (as shown in the picture) to reduce gradient
interference.
Position and connect the PERU and electrodes as usual. Then use
the electrodes as a pivot point and turn the PERU with the
application cushion counterclockwise until the cushion is lying next
to the patient's head.

ECG triggering

Description

ECG triggering is a method for measuring heart sequences including
dynamic studies. It is also suitable for studies where pulse flow causes
artifacts. Provided that special sequences are in use, ECG triggering
can be applied in combination with respiratory-controlled methods.
A number of special sequences support retrospective gating.
The ECG leads are selected according to the potential difference
between the connected electrodes.
The three leads I, II and III are used and acquired in parallel via the
ECG channels. All curves display a prominent R wave when the ECG
electrodes and leads are correctly attached.
