    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： The present invention relates to a method and to a device for visualizing objects, in particular non-rigid objects. The method and the device are particularly suitable to visualizing three-dimensional objects in the case of medical interventions.The method comprises: providing a three-dimensional image data record of the object, successively taking a series of two-dimensional image data records of the object, individually registering each individual two-dimensional image data record with the three-dimensional image data record, functionally evaluating functional parameters from the successively taken two-dimensional images, extracting two-dimensional projections from the three-dimensional image data record, and superimposing the recorded two-dimensional images with the extracted two-dimensional projections. A clean copy of the abstract that incorporates the above amendments is provided herewith on a separate page.

    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.
