摘要： A method is disclosed for obtaining a 4D image data record of an object under examination using measured data from a computed tomography system in which projection data are accepted which were acquired by way of the computed tomography system at different imaging time points by way of an helical scan method following the administration of contrast medium to the object under examination). On the basis of the projection data, image data of the object under examination are then reconstructed and linked with the imaging time points to a space/time data record. Then, a parameterized 4D image data model is individualized with adaptation to the space/time data record by varying model parameters. An image processing device and a computed tomography system with an image processing device of this kind are also described.

摘要： A method and a data-processing system are disclosed for determining the proportion of calcium in coronary arteries using image data from CT angiography. In at least one embodiment of the method, anatomical landmarks are detected in the image data in the region of the heart and coronary arteries are segmented taking into account the detected landmarks. Regions with an increased HU value compared to a contrast agent surroundings are segmented in the segmented coronary arteries. A proportion of calcium respectively is calculated from the segmented regions for one or more of the segmented coronary arteries. At least the last two steps are carried out fully automatically by a data-processing system. Weighting factors for the individual regions are used when calculating the proportion of calcium, which weighting factors depend on both the threshold for segmenting the respective region and the volume of said region. The method and the data-processing system of at least one embodiment allow the dose exposure of the patient to be reduced and reduce the time expenditure of the user for determining the proportion of calcium.

摘要： The invention relates to a method for navigating a catheter with a catheter tip through a blockage region in a vessel, especially a coronary vessel, whereby the catheter is pushed forward under real-time radiological observation. The underlying objective of the invention is to arrange such a method in such a way that it permits especially simple, rapid and low risk navigation of a catheter through the blockage region in the vessel. For this purpose, in accordance with the invention a three-dimensional path through the blockage region is determined by reference to a set of sectional images or a 3D representation of the blockage region, recorded beforehand as part of a preliminary investigation, whereby a data set including the path coordinates is brought into register with the real-time radiological images, and whereby the path or a projection of the path is visualized on a display, overlaid on the real-time radiological images.A clean copy of the abstract that incorporates the above amendments is provided herewith on a separate page.

摘要： Embodiments are described herein for determining anatomical landmarks on a patient by virtue of anatomical landmarks being called up from a database with an anatomical model and being converted into individual body dimensions and an individual position of the patient. As a result, anatomical landmarks may be called up from a database, calculated individually for the patient and used as an item of reference location information. The positioning of the patient table is thus considerably accelerated, wherein the accuracy is also improved. Thus, the item of reference location information may be calculated individually for the same patient in a different position or a different patient with different body dimensions by virtue of this item of reference location information being recalculated by the conversion rule for the respective patient.

摘要： The automated positioning of an examination table relative to a medical-technical imaging installation is provided. A camera image is frozen by a first user interaction. Reference information is defined in the frozen camera image by a second user interaction. An examination table or medical-technical imaging installation with the aid of a positioning system is moved based on congruence between the reference location information with a recording region of the medical-technical imaging installation.

摘要： A method and a system are disclosed for computed tomography illustration of the movement of a heart in the cardiac cycle with the aid of a spiral CT. In the method, a patient is administered a contrast medium via an electronically controllable apparatus. A stationary prescan of a cardiac artery is carried out in order to determine the sufficient filling of the artery with the automatically applied contrast medium. When a sufficient contrast medium filling is detected, the current heart rate of the heart being examined is measured, and a maximum possible feed rate for a spiral scan and a duration of the spiral scan are determined on the basis of the current heart rate. Subsequently, the spiral scan is carried out over the heart region with the maximum possible feed rate.
