    摘要: A recording arrangement of an x-ray system comprises an x-ray source and an x-ray detector. Adjustment parameters can be manually supplied to the recording arrangement by an operator of the x-ray system, so that the x-ray source emits x-rays according to the manually given adjustment parameters and the x-ray detector accordingly acquires a sequence of images of an object. The manually supplied adjustment parameters can be automatically acquired by an acquisition device and stored in a remanent memory at least temporarily assigned to the acquisition device and remain stored after the completion of the acquisition of the sequence independently of a further operation of the x-ray system. The stored adjustment parameters can be retrieved from the remanent memory by the operator and supplied again to the recording arrangement so that a further sequence of images can be acquired according to the retrieved adjustment parameters.

    摘要: A controller of an image-generating medical engineering assembly receives a selection of an image valuation method from a user. It subsequently automatically adjusts selection-specific, positioning-independent operating parameters of the recording arrangement and or provides the user with instructions for adjusting the positioning-independent operating parameters. In response to a user's start input the controller captures by means of a recording arrangement of the image-generating medical engineering assembly a sequence of successive two-dimensional images of an iteratively moving object being examined and capturing instants thereof as well as a phase signal of the object being examined and archives the sequence of images, capturing instants and the phase signal.

    摘要: A device for the magnet-assisted catheter intervention comprises magnets for controlling a magnetic tip of a catheter. An x-ray device serves to generate three dimensional ambient images of a patient. A data processing unit calculates the probability of the magnetic tip colliding with an obstacle in the body of the patient from the ambient images and the current position of the magnetic tip and if necessary acts mechanically on the guide element so as to generate a haptically perceivable signal, with which guide element the movement of the catheter is controlled.

    摘要: Data of an examination object comprises a volume-data record and a plurality of two-dimensional projection images. The volume-data record includes voxels where each voxel is assigned to a location in three-dimensional space. Each projection image includes pixels where each pixel is assigned to a location in a two-dimensional-projection plane and has a value. Each pixel is assigned a projection volume, this being specified in that it is mapped by the radioscopy onto the pixel to which it is assigned. A sub-volume of the volume-data record is selected. The projection images are registered in relation to the volume-data record. A functional parameter of the examination object is specified for the pixels of the projection images, depending on their values. For each pixel, when specifying the functional parameter, consideration is given to the locations and/or the number of those voxels which are positioned both within the sub-volume and within the projection volume.

    摘要: 2-D projection images show the temporal profile of the distribution of a contrast medium in an examination object, which contains a vascular system and its surroundings. Each projection image comprises pixels with pixel values. The pixel values of pixels corresponding to one another in the projection images are defined by at least essentially locationally identical areas of the examination object. A computer assigns a uniform 2-D evaluation core that is uniform for all corresponding pixels at least in a sub-area of pixels corresponding to one another in the projection images that is uniform for the projection images. The computer defines at least one characteristic value for each pixel within each projection image based on the evaluation core assigned to the pixel and assigns it to the relevant pixel. Based on the temporal profile of the characteristic values, the computer defines parameters of at least one function of time, so that any deviation between the function parameterized with the parameters and the temporal profile of the characteristic values is minimized. Based on the parameters the computer defines a type and/or an extent and assigns them to a pixel of a 2-D evaluation image corresponding to the pixels of the projection images. The type indicates whether the respective pixel of the evaluation image corresponds to a vessel of the vascular system, a perfused part or a non-perfused part of the surroundings of a vessel of the vascular system. The extent is characteristic of perfusion. The computer outputs at least the sub-area of the evaluation image to a user via a display device.
