Abstract: A computed tomography unit and a method are disclosed, for a computed tomography unit having at least one marking device for the positionally accurate marking of an intervention position by way of a laser beam on an object to be examined. The at least one marking device is assigned to a rotary frame of the computed tomography unit and is arranged directly in a recording plane of a recording system. As such, a positionally accurate marking of an intervention position with the aid of simple devices/methods is possible without a large numerical outlay, particularly even during operation of the computed tomography unit, that is say during a rotational movement of the rotary frame.

Abstract: A method is disclosed for obtaining a 4D image data record of an object under examination using measured data from a computed tomography system in which projection data are accepted which were acquired by way of the computed tomography system at different imaging time points by way of an helical scan method following the administration of contrast medium to the object under examination). On the basis of the projection data, image data of the object under examination are then reconstructed and linked with the imaging time points to a space/time data record. Then, a parameterized 4D image data model is individualized with adaptation to the space/time data record by varying model parameters. An image processing device and a computed tomography system with an image processing device of this kind are also described.

Abstract: In a method and device for planning a medical imaging, a number of quality parameters that associate a desired image quality with the image exposure are imported into an image acquisition of an examination region that can be executed by means of an image acquisition apparatus. A number of image acquisition parameters are determined and, using the image acquisition parameters, an achievable image quality of the image exposure is concluded under consideration of an apparatus variable. The achievable image quality is compared per image region with the desired image quality and, if the achievable image quality falls short of the desired image quality, a shortfall indicator is output relative to the image region.
