Abstract

Systems (100,110,500,900) and methods for medical imaging may be provided. A respiratory amplitude of a respiratory motion of a subject during a medical scan may be determined based on a respiratory signal relating to the respiratory motion. The respiratory signal may be collected using a respiratory motion detector (120,510,820) by emitting detecting signals toward a target region of the subject. Surface information of the target region may be obtained. The respiratory amplitude may be corrected based on the surface information of the target region.
