Motion Compensation in Nuclear Imaging
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.
