4 Align the PERU on the patient in the direction of the foot end of the
patient table (even though the patient may have been positioned
Feet First).
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. Now turn the clips counterclockwise, so that
the cable outlet of the clips is positioned in the direction of the
patient's head.
ā or ā
As an alternative (for example, if the patient is wearing a shirt),
first position the PERU with the application cushion next to the
patient's head and then run the cables through the neckline of the
patient's shirt to attach the electrodes. Try to avoid cable loops.
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.
