摘要: The invention relates to methods and systems for compensating for respiratory motion of individuals during nuclear imaging. In some embodiments, the methods include obtaining data representing a reference respiratory state for the individual and obtaining data that represents a plurality of respiratory states that correspond to at least a portion of a cycle of respiration of the individual; comparing each of the plurality of respiratory states to a subset of the reference state data to obtain a motion estimate of each of the plurality of respiratory states; compensating for respiratory motion in each of the plurality of respiratory states based on the motion estimates to obtain motion-compensated respiratory state data; and constructing an image using the motion-compensated respiratory state data.
