Abstract
The invention relates to a pivotal poly-plane imaging unit having a first and a second imaging planes arranged relative to each other at an offset angle and recording projection images of an moving examination object at a fan angle β. First and second projection images are recorded in different relative positions at respective instants by pivoting the imaging planes at an angle at least 180°+β. Characteristic structures in the first and second projection images are detected. The characteristic structures are segmented by a vectorial representation and triangulated to obtain a three-dimensional representation of the characteristic structures. Three-dimensional displacement vector fields are determined that indicate displacements of the three-dimensional representation of the characteristic structures relative to a reference instant. A three-dimensional image is reconstructed using the three-dimensional displacement vector fields to display a state of the moving examination object at the reference instant.
