Method for image-based motion correction i.e. breathing motion correction, in two-dimensional radioscopy image during medical needle intervention of patients, involves visualizing fluoroscopy images such that images are corrected

摘要

The method involves determining motion of patients in the form of translation and rotation from two-dimensional (2D) images in viewable fluoroscopy images (27) during medical intervention of patients. Virtual elongations of the fluoroscopy images are evaluated for searching processes in different fluoroscopy images or frames. A virtual rotation center (Z) is determined by sectioning of the elongations. The fluoroscopy images together with three-dimensional (3D) images are visualized such that the 3D-images and/or the fluoroscopy images of the evaluated shift are corrected accordingly.
