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.

The system and method includes hardware and software for determining physiological characteristics of a patient and determining imaging parameter values for an imaging modality based on the patient's physiological characteristics. The system also includes a controller operative to receive the imaging parameter values for controlling an X-ray device. The X-ray device is coupled with the controller and acquires projection images of the patient, and outputs the projection images to a perfusion evaluation computer for evaluating the perfusion of an region of interest represented in the projection images. The perfusion rate of the region of interest is then output to an output device, such as a display or printer.

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.
