Abstract

The disclosure relates to a method for recording a panorama dataset of an examination object by a movable medical x-ray device, to a medical x-ray device, and to a computer program product for carrying out the method. The medical x-ray device has an x-ray source, which emits a bundle of x-rays, wherein a first image segment, which maps at least one part of the examination object, is recorded at a first point in time. Position data is acquired, which maps the spatial position of the x-ray device at this first point in time. At least one further image segment along an imaging path is recorded after there has been a movement of the x-ray device, wherein the imaging path lies in one plane, wherein a central ray of the bundle of x-rays emitted by the x-ray source does not run in parallel to the plane in which the imaging path lies. Additionally, position data is acquired, which maps the spatial position of the x-ray device at the time of the recording of the at least one further image segment. The acquired position data is uniquely assigned to the recorded image segments. The panorama dataset is assembled from at least two image segments with the position data assigned thereto from a se…
