According to an embodiment of the application, a method is provided for selecting an algorithm for correcting at least one image artifact in an image data record acquired by a medical imaging system and representing at least one region of interest of a subject under examination. The method includes identifying from the image data record at least one object element causing the image artifact and lying inside the region of interest of the subject under examination; determining from the image data record at least one characteristic describing the object element; determining an artifact correction algorithm on the basis of the at least one characteristic; and applying the artifact correction algorithm to the image data record. An embodiment of the application also provides a corresponding data processing facility and a medical imaging system.

An imaging facility having an X-ray source, an X-ray detector, and a rotation facility operable to rotate the X-ray source and the X-ray detector around a center of rotation. The imaging facility also has a first translation facility operable to move the X-ray source in a direction that has a component that is tangential to a circle of rotation around the center of rotation.

Imaging facility and radiation therapy device

A method for determining a movement phase of a periodically moving object in a plurality of sequentially produced images in a series of images of the periodically moving object. The method includes registering different images in the series of images. The method also includes determining a deformation that has occurred between the registered images. The method further includes&#x2014;determining the phase of the movement of the moving object for at least one of the images in the series of images based upon the determined deformation.
