摘要

While the present invention generally, CT-based are mentioned imaging system, and is moved in particular tissue region M to be object of interest O or inspection continuously tube around (herein "target" also known), referring to the high-speed 3D tomosynthesis scanner apparatus and CT-based method not move the focus, this is in order to avoid motion artifacts and blur effect, it may be advantageously used with the cone-beam volume CT mammography imaging. According to the invention, the 3D tomosynthesis scanner apparatus, the object O, when rotating around the M, 2D during the rotational movement of the continuous X-ray tube 101 is azimuthally + φ along an arc of a circular path It performs a rotary step-and-shoot image acquisition for acquiring a set of projection images, it is suitable for applying these 2D projection images to a 3D reconstruction procedure. According to the invention, in the image during the acquisition time for each 2D projection image, the prediction and the focus on the anode of the X-ray tube with respect to the rotation from the starting position b _s to the end position b _e move in the opposite direction -φ differentially.
