Abstract: A computer-implemented method for generating control information for the remote control of an intervention device that is to be used during an intervention, for example a medical intervention, at an intervention location, wherein at least one first person is present at the intervention location and at least one second person is present at a location which differs from and is remote from the intervention location for the purpose of cooperation during the performance of the intervention, and control information provided by the second person is sent from the remote location to the intervention location by a communication connection, wherein use of the control information for controlling the intervention device is only enabled if a safeguarding signal, which indicates a monitoring activity of the first person and is output by a signaling device that may be activated by the first person, is present.

Abstract: A method is provided for operating a medical X-ray device when carrying out an X-ray examination. In order to reduce the duration of the scan for the reliable determination of changes over time in a body region of an examination subject by an X-ray based subtraction method, the method includes recording a plurality of first X-ray images of a body region of an examination subject, wherein the recording of the plurality of first X-ray images ensues at a constant X-ray imaging frequency and a constant X-ray dose for each X-ray image recording.

Abstract: Operating a medical image recording device in the context of an image recording routine for a patient is provided. The image recording routine serves an image recording purpose. The image recording device is controlled based on operating parameters implemented by a controller of the image recording device. The operating parameters are identified completely automatically by an identification algorithm from input data describing at least the patient in the form of a patient model and/or the image recording purpose, and from a registration of the patient with a coordinates system of the image recording device. The operating parameters are used to control the image recording device. An examination region that is to be recorded for the patient and the image recording purpose are derived based on the registration.

Abstract: The disclosure relates to a method and an imaging device for generating a new roadmap image of a target object. For the method, a first subtraction image is generated from a first mask image and a contrast agent image of the target object. A parameter value of a parameter of the imaging device that affects the acquisition of images by the device is then changed. A third mask image of the target object is acquired automatically by the imaging device using the changed parameter value. From a second examination image subsequently acquired using the changed parameter value, a third subtraction image is generated by subtraction of the third mask image. The new roadmap image is generated using the first subtraction image and the third subtraction image.
