摘要：
A method of detection and compensation for respiratory motion improves the registration between a 3D pre-operation image and X-ray images acquired during a cardiac intervention. By synchronizing the X-ray images with the electrocardiogram, the disclosed method thus eliminates the motion related to the heart cycle from these images, thus isolating the contribution of the respiratory motion. From this point, an algorithm is proposed capable of attributing the motion remaining in the radiography images to respiration. The algorithm also enables this motion to be detected and compensated for in order to obtain a registration between 3D cardiac images and radiography images.
