摘要： A method for segmenting a two-dimensional angiographic recording of a vessel of a body using a computing apparatus includes providing a three-dimensional reconstruction of the vessel of the body to the computing apparatus. The two-dimensional angiographic recording of the vessel of the body is provided on the computing apparatus. The three-dimensional reconstruction of the vessel of the body is registered with the two-dimensional recording of the vessel of the body. Spatial information of the three-dimensional reconstruction is projected onto the two-dimensional recording, and the two-dimensional recording is segmented using the spatial information projected onto the two-dimensional recording.

摘要： A method for planning treatment of a stenosis in a vascular segment includes providing a geometric description of the vascular segment on a computer and determining a course of a hemodynamic parameter of the vascular segment along the vascular segment based on the geometric description provided by the computer. The computer calculates a mathematical derivative of the hemodynamic parameter over the length of the vascular segment along the vascular segment. At least one length section is specified for the vascular segment, and a value of the hemodynamic parameter in a distal end region of the vascular segment is simulated for a treatment device introduced virtually into the specified length section as a function of the mathematical derivative. The treatment of the stenosis including the introduction of the treatment device into the specified length section is planned as a function of the simulated value for the hemodynamic parameter.

摘要： A method and system for operating an x-ray device for a creation of a three-dimensional angiography of a body vessel segment. A three-dimensional reconstruction of the body vessel segment is provided to a computing device of the x-ray device. A center line of the body vessel segment is computed. An axis of rotation is laid through the center line. The three-dimensional reconstruction is registered with the x-ray device. The suitability of at least one recording angle pair with a first and a second recording angle for the creation of the three-dimensional angiography is assessed on the basis of an assessment criterion by the computing device. One of the at least one assessed recording angle pairs is selected for creation of the three-dimensional angiography as a function of a result of the assessment, in order to improve the creation of the three-dimensional angiography.

摘要： An angiographic examination method for the representation of flow properties of vessels of an object under examination is presented. To determine blood-flow parameters in 3-D with high temporal resolution, at least one 4-D DSA sequence is acquired for the generation of measurement-based 4-D DSA data sets. A model-based method determines time-dependent volume data sets, which, in terms of time, lie between the time-dependent volume data sets of the measurement-based 4-D DSA method.

摘要： A system and method for obtaining perfusion images is disclosed. 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.
