Summary

The estimation and quantification of motion in moving organs, such as heart and lungs, is one of the main objectives under focus in the analysis of medical images concurrently with image segmentation. The problem of motion estimation and analysis has been the subject of many developments in computer vision in application domains initially quite different from medical imaging (analysis of scenes by optical camera). Many methodological developments have been made in medical imaging to ensure geometric matching (or registration) between two images. Generally, the two images represent the same group of organs observed with two different modalities (intermodality registration). The quantitative analysis of cardiac and thoracic kinetics is made possible by accessing data increasingly more resolved in space and time and the imaging development of an arsenal of more or less complex methods adapted to modalities. Motion quantification allows the “normal” dynamic behavior to be characterized.
