Abstract: The invention relates to a method for determining an X-ray image dataset of a target region of an object to be examined, wherein projection images showing the target region are captured by means of an X-ray detector and the X-ray image dataset is reconstructed from the projection images, wherein a first portion of the projection images is captured so as to be collimated onto the target region by the target region being irradiated with X-ray radiation by means of an X-ray device through at least one main radiation opening of a collimator assembly. The invention also relates to a corresponding apparatus for determining an X-ray image dataset of a target region of the object to be examined. The invention generally relates to the field of medical X-ray imaging, in particular with the aim of acquiring projections for reconstructing 2D computed-tomography images.

Abstract: Embodiments can provide a visual indicator system, attachable to a medical imaging patient bed. The visual indicator system comprising: one or more light strips, each light strip comprising a plurality of lights; a distance meter, attachable to one end of the medical imaging patient bed; a storage device, configured to store one or more preconfigured finger gestures; and a microcontroller. The one or more light strips are attachable to the medical imaging patient bed; wherein the microcontroller is configured to illuminate the one or more light strips after the one or more preconfigured finger gestures are made with respect to the one or more light strips. A position of the illumination of the light strip corresponds to a position of performing the one or more preconfigured finger gestures and one or more distance measurements received from the distance meter.
