    摘要: A sequence of groups of projection images shows an object under examination comprising a vascular system and its environment. A computer determines a 2-dimensional evaluation image having a plurality of pixels based on combination images determined from the projection images of a group. The combination images have a plurality of pixels with pixel values. The sequence of the combination images shows the time characteristic of the distribution of a contrast medium in the object. The pixels of the evaluation image correspond to those of the projection images. The computer assigns each pixel, at least in a part area of the evaluation image, a type that is characteristic of whether the respective pixel corresponds to a vessel of the vascular system, a perfusion area or a background. It performs the assignment of the type on the basis of the time characteristic of the pixel values of the combination images.

    摘要: There is described an analysis method for at least one image data record of an examination object, wherein each image data record features a multiplicity of image data elements. A position in a multidimensional space is assigned to each image data element. Each image data element features an image data value. The image data values of positionally corresponding image data elements of the image data records are specified by means of at least essentially positionally identical regions of the examination object. A computer automatically divides the image data records into empty regions and signal regions, applying an overall assignment rule which is based on the image data values of the image data elements of a plurality of image data records, such that each image data element of each image data record is assigned to either its empty region or its signal region. For each image data record, the computer automatically determines a closed outline which fully contains the signal region of the relevant image data record and, on the basis of the closed outline of the relevant image data record, determines an analysis region such that a further analysis of the relevant image data record can be restricted to its analysis region.

    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: 2-D projection images show the variation over time of the distribution of a contrast medium in an examination subject. Each projection image comprises pixels having pixel values corresponding to one another in the projection images that are determined by identical areas of the examination subject. A computer subdivides an image that is to be displayed from the projection images into parcels in one perfusion region. For each parcel, the computer determines a characteristic value and, based on the characteristic value, a projection color. It assigns the projection color to the parcel. The characteristic value is determined based on the pixel values occurring in the parcel of the projection image or their differences from the pixel values of a corresponding parcel of another projection image. The computer outputs a subarea of the projection image containing the perfusion region. It represents each parcel of the perfusion region in its assigned projection color.

    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.

Each projection image has pixels with pixel values defined by the same areas of the examination object a computer determines a 2-D evaluation image having pixels corresponding to those of the projection images and assigns each pixel in a sub-area, to one of three types, perfused part of the surroundings or non-perfused part of the surroundings assigns, an extent of a perfusion in the pixels of the evaluation image assigned the type of perfused part of the surroundings to the respective pixel. The type and extend are determined from the temporal course of the pixel values of the pixels of the projection image which is in a two-dimensional evaluation core defined by a respective pixel of the evaluation image.
