Respiratory triggering
Description
To keep respiratory artifacts to a minimum, respiratory triggering is
primarily used in abdominal imaging. Data acquisition for respiratory
triggering begins when the respiratory signal reaches a predefined
level (approx. 20 % of the maximum value). Respiratory movement is
minimal in this range.
(1) Expiration
(2) Inspiration
The respiratory signal is acquired using a respiratory cushion
connected via a pressure hose to the ECG and respiratory sensor
(PERU). The respiratory cushion is attached to the patient via the
respiratory belt.
Retrospective gating cannot be applied.
Performing
1 Ask the patient to lie still during the measurement.
2 Inform the patient that the knocking sounds during the
measurement are caused by switching the gradients on and off.
The PERU may also vibrate slightly.
