Respiratory Gating
Respiratory gating
The respiration of the patients is simultaneously
recorded during the Spiral acquisition.
Data are acquired during the entire respiration cycle
and Images are reconstructed by matching data to the
respiration trace.
The respiration level (amplitude) is defined as an abso-
lute value. The display of the respiratory curve is opti-
mized by an auto adjustment regarding
• Gain (showing inspiration maximum as 100% of
inspiration and expiration minimum as 100% of
expiration)
and
• Offset (showing the curve optimal to vertical display
extent).
