Abstract: A method and system for providing a mask image including receiving medical image data including a temporal dimension and generating a frequency data set including data points with in each case one frequency value by applying a Fourier transform to the image data. The Fourier transform is applied at least along the temporal dimension. The frequency data set is segmented into two sub-areas based on at least a frequency threshold value. The mask image is generated by applying an inverse Fourier transform to the first and/or the second sub-area of the frequency data set. The generated mask image is provided.

Abstract: A method is provided for multi-energy X-ray imaging of a field of view in order to display a contrast material, located in the field of view, having an atomic number of at least 65, (e.g., at least 73), and/or a k-edge of at least 60 keV. In the method, two image datasets having different X-ray spectra are recorded and are combined in order to ascertain display information of the contrast material, wherein the X-ray spectra are generated by using at least one spectrally acting filter, starting from a source spectrum of an X-ray source in such a way that the value of their differential spectrum has a maximum, which includes a range, beginning at the k-edge of the contrast material, of higher absorption by the contrast material.

Abstract: A method for determining at least one competency relationship to be used as a basis for selection of a dose-related recording parameter for an examination process, in particular the recording of a timed series of x-ray images as an x-ray image dataset, of a patient at an x-ray device, between at least one competency value describing a user-specific or user-group specific user competency in respect of the evaluation of recorded x-ray images and at least the at least one recording parameter. The method includes displaying a plurality of x-ray image datasets corresponding to different recording parameters and/or having different image contents described by image content parameters; recording, for each x-ray image dataset, at least one measured value describing the competency value based on an interaction of a user with an operating device assigned to a display device; and determining, based on the measured values, the competency relationship describing the recording parameter-dependent competency value.

Abstract: A device for moving a medical object, the device including a mover device and a sensor unit. The mover device is configured to hold and/or move a medical object at least partially disposed in the mover device by transmitting a force. The sensor unit is configured to detect a counterforce exerted by the medical object on the mover device and acting in the opposite direction to the force. The medical object is at least partially disposed in an examination subject. The device is configured to provide a signal as a function of the counterforce. The mover device is configured to move the medical object as a function of the signal.

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.

The anti-scatter grid includes a plurality of X-ray absorption plates and a carrier body to which the plurality of X-ray absorption plates are fastened. The carrier body is embodied in a meander shape with a plurality of linearly extending subsections and curve sections connecting the plurality of linearly extending subsection with one another. At least one X-ray absorption plate is arranged in each linearly extending subsection of the plurality of linearly extending subsections.

Abstract: A computer-implemented method for processing x-ray images. A sequence of x-ray images is provided of a field of view in which at least one section of a vascular system of an examination subjects is imaged. The sequence describes a variation with time of the detected x-ray intensity in the field of view based on a change in a contrast agent distribution in the section of the vascular system. A contrast agent variable is determined relating to the contrast agent distribution as a function of a variation with time of a variable relating to the x-ray intensity in a selected subregion of the x-ray images. An image of the section of the vascular system is determined as a function of at least one of the x-ray images of the sequence. The image is modified as a function of the contrast agent variable.
