Abstract: A computer-implemented method for evaluating an X-ray image includes: segmenting the hollow organ structure in the X-ray image; determining center lines and edge boundaries of the segmented hollow organ structure and ascertaining a diameter of each hollow organ along its center line; ascertaining an image absorption value, describing the increase in absorption due to a contrast agent in the hollow organ compared to surroundings of the hollow organ, along the center line of each hollow organ; ascertaining, for each image absorption value, a theoretical computing absorption value expected when the hollow organ is completely filled with the contrast agent, by using at least the diameter and contrast agent information; determining a filling level along the center line of each hollow organ of the hollow organ structure by comparing the image absorption value with the computing absorption value; and outputting filling level information including the filling levels.

Abstract: A device for radiation therapy implemented with image monitoring has a magnetic resonance device and an exposure device. The magnetic resonance device has a magnet and primarily serves for image monitoring an examination object of a patient in an examination volume of the magnetic resonance device. The exposure is fashioned to be static and serves to expose the examination subject in the examination volume with therapeutic beams. The patient (and therefore the examination subject) are supported by a patient positioning device such that the examination subject can be moved relative to the magnetic resonance device and the exposure device around at least one rotation axis.
