摘要： The invention relates to a method and an apparatus for correcting dynamic models (4) of moving structures (2), said dynamic models being obtained by tracking methods. The method comprises the following steps: (a) providing a time series of images (B) of the moving structure (2) recorded successively in time; (b) providing a dynamic model (4) of the structure (2), said dynamic model being obtained by a tracking method; (c) determining a position time section (h) in the images (B); (d) providing a position-time representation (6) over time of the optionally interpolated image values of the position time section (h) in the images, combined with a representation of the dynamic model (4) as at least one computer graphical object (10); (e) comparing the computer graphical object (10) with the surrounding image content (8), in particular by a user, and (f) correcting the dynamic model (4) by editing the at least one computer graphical object (10), in particular by a user.

摘要： The invention relates to the adaptation of a 3D-surface model to boundaries of an anatomical structure, especially the right ventricle. A first viewing plane is defined corresponding to a default view, especially a four chamber view. A long axis is defined. Then a second, third and optionally a fourth viewing plane are represented intersecting the axis in predefined distances from the starting point and end point thereof. On the viewing planes different markers are represented, controlled and, if required, the position thereof is adapted, especially the position of the intersection points of the axis with the second and third viewing planes, as well as the position of a characteristic line, which together with the end point of the axis spans a characteristic plane of the structure. The 3D-surface model is adapted to the structure by way of the long axis and the position of the characteristic plane.
