摘要： In a method and apparatus for optically-based acquisition of slice images from a vessel of a subject, and for combining the slice images to provide an intuitively recognizable visualization of a pathology in the vessel, slice images of the vessel are acquired during pullback of an optical probe of the optically-based slice imaging system, while simultaneously acquiring an ECG signal from the subject. The slice images and the ECG signal are registered, and slice images acquired at a selected cardiac phase are combined into a scene. The slice images in the scene are subjected to a first data transformation to shift the vessel midpoint in each slice image to the image center of each slice image. After the first data transformation, the slice images in the scene are subjected to a second data transformation to produce the visualization. The second transformation, for example, can be a curved planar reformation to allow the vessel to be shown in longitudinal section.

摘要： A trigger device feeds to a control device for a medical imaging system a number of trigger pulses which all correspond to a predetermined phase angle of an object, e.g. of a heart which is the same for all trigger pulses. The control device activates an image recording device at least on the basis of a few of the trigger pulses so that the image recording device records a sequence of images of the object in each case, as from a start time relative to the initiating trigger pulse and ends the recording of the sequence at a stop time, so that the images (Bk) of this sequence have predetermined time offsets to the initiating trigger pulse. The control device determines the stop time such that it lies before a start time which is determined on the basis of the trigger pulse immediately following the initiating trigger pulse. The image recording device feeds the recorded sequences to the control device which stores the sequences fed to it.

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.
