摘要
A method and system for detecting the presence of motion in functional medical imaging data by comparison with anatomical medical imaging data derived from reconstructed anatomical images. Detected motion in the functional data is then estimated and corrected. In accordance with an example embodiment, CT object templates are produced from reconstructed CT image data and convolved with nuclear medical (SPECT or PET) projection data to detect object motion. Detected motion is estimated to obtain a displacement vector, and the nuclear medical projection data is corrected for objection motion by application of the displacement vector.
