摘要：
A respiratory marker (40, 140, 240, 340, 440) includes an elongated detectable portion (42, 342, 442) that is operatively coupled with respiration of an imaging subject such that the elongated detectable portion moves with the respiration. The elongated detectable portion is arranged to intersect images acquired by an imaging scanner (10) at different times and at different positions along a scanner axis (20), and is detectable as a marker feature in the images. A marker position finder (52, 54) is configured to determine positions of the marker features in the images.
