摘要： There is described a method for determining an optimal trigger time for an ECG-triggered recording of an object. In this respect, a time sequence of dynamic images is firstly acquired with simultaneous recording of an ECG signal, then a time in the cardiac cycle is assigned to each dynamic image, and finally the dynamic images are analyzed, for example by calculation of a degree of similarity, in order to identify the time of minimal movement of the object within the time sequence.

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： Two 3D image data records are obtained mutually independently comprising healthy myocardium, myocardium having a reduced blood supply, and the necrotic myocardium. The image data records are combined to produce an overall image data record after registration, and 2D image representations are produced from the overall image data record in which the necrotic parts of the myocardium are shown emphasized, with simultaneously showing the endocardium or the healthy parts of the myocardium and parts having a reduced blood supply. The overall image data record can be used afterwards. For example, further registering step is carried out using images obtained during an intervention on the myocardium. The further registering step enables the necrotic parts of the myocardium to be assigned to the patient's situation. That can extend as far as catheters being moved automatically up to a boundary of the necrotic myocardium.

摘要： The invention relates to a method or x-ray device for creating a series of two-dimensional medical x-ray images to be related to each other in an evaluation of a patient with initially a first x-ray image and subsequently a further x-ray image being created, a deviation caused by a patient movement in each case between the further x-ray image and an x-ray image of the previously created x-ray images being determined and a relative position between an x-ray emitter and x-ray detector used to create the x-ray images and the patient being set in the sense of compensating for the patient movement depending on the relevant deviation, in order to guarantee over the entire extent of the series recording x-ray images which can be related to each other with few errors in an inexpensive manner despite movement of the patient.

摘要： The present invention relates to a method for determining the position of an instrument in a structure of an object with an x-ray system, in which a 3D image data record is provided for at least one area of the object relevant for determining the position, the x-ray system is registered with the 3D image data record, after the introduction of the instrument into the structure at least one 2D x-ray image of the relevant area is recorded from at least one direction of projection with a known projection geometry with the x-ray system and a 2D position of a first location of the instrument is recorded in the 2D x-ray image. In the method a projection line in accordance with the known projection geometry is placed through the 3D image data record at the 2D position and a 3D position of the first location of the instrument in the 3D image data record is determined from an intersection of the projection line with the structure. The method enables the 3D position to be determined with a simple monoplanar x-ray system.

摘要： The present invention relates to a method to compensate for patient motion in series recordings in medical imaging, in which a plurality of images of an examination area of a patient (17) are recorded at time intervals with an imaging system (1) and related to each other. The invention also relates to an imaging system (1) for implementing the method. With the method, before the start of the series recordings a 3D image data set is recorded by a 3D recording of the examination area, which establishes a reference system. A first spatial position of the examination area in the reference system is then either obtained by recording a first image of the series recordings and registering it with the 3D image data set or by calculating it from a known calibration of the imaging system (1). Each further image of the series recordings is registered immediately after recording with the 3D image data set, to obtain the current spatial position of the examination area in the reference system. Finally a difference in respect of the first spatial position is determined and at least some of the difference is compensated for at least approximately by changing geometric relationships of the imaging system (1) in temporal proximity to registration. The method allows patient motion to be compensated for without interaction by the user of the imaging system.

摘要： A method and system for extracting a silhouette of a 3D mesh representing an anatomical structure is disclosed. The 3D mesh is projected to two dimensions. Silhouette candidate edges are generated in the projected mesh by pruning edges and mesh points based on topology analysis of the projected mesh. Each silhouette candidate edge that intersects with another edge in the projected mesh is split into two silhouette candidate edges. The silhouette is extracted using an edge following process on the silhouette candidate edges.

摘要： An X-ray imaging apparatus has at least one X-ray image system rotatable about an examination volume. The X-ray image system is controlled such that during a continuous rotation of the system, at least one 2D projection image is recorded. An image generation facility generates the 2D projection image from the measured data. The X-ray source includes an X-ray focus which can be changed in terms of position, which, during the recording of the 2D projection image, moves counter to the direction of rotation of the X-ray image system such that its spatial position in a fixed coordinate system does not change. The X-ray detector records several 2D partial images, from which the 2D projection image is calculated with the rotational movement of the X-ray detector being at least approximately compensated. The 2D projection images have significantly reduced image blur.
