摘要： A method as a workflow for imaging for a heart valve implant procedure includes positioning the patient and an articulated imaging apparatus relative to one another, inducing rapid ventricular pacing in the patient, and imaging a region of the patient's heart to obtain image date for a three-dimensional image. The three-dimensional data is used to construct a three-dimensional image of the region of the patient's heart an the three-dimensional image is displayed for use in the implanting of the replacement heart valve. Optional steps may include obtaining a real time two-dimensional image of the patient's heart and superimposing the real time two-dimensional image with the constructed three dimensional image. The replacement valve is moved into position in the patient's heart during rapid ventricular pacing and breath hold using the superimposed two-dimensional and three-dimensional image information.

摘要： In a method and system for patient-specific production of a cardiac electrode lead, a 3D representation of the coronary sinus vessel tree is segmented to indicate the interior surface thereof and a representative line from an opening of the coronary sinus vessel tree to an implantation site for the electrode lead, and a computerized model of the electrode is generated that includes deformation properties of the mechanical structure of the electrode lead. A computerized virtual implantation of the electrode through the 3D representation of the coronary sinus vessel tree is implemented using the model and the internal surface and the representative line from which determination is made as to whether an electrode conforming to the model can be guided to and implanted at the implantation site in a medically acceptable manner, or whether modification of the electrode lead is necessary.

摘要： A method and a device for obtaining a volume data set of a mobile tissue or organ of a patient by a C-arm X-ray device are provided. An electromagnetic sensor of a position detection system is arranged indirectly on the tissue or organ. The X-ray device obtains a plurality of X-ray projections from the tissue or organ from various projection directions. A first method consists of reconstructing a volume data set from the X-ray projections, in which the electromagnetic sensor adopts a position characterizing a displacement phase of the tissue or organ. A second method consists of reconstructing a volume data set from the X-ray projections captured when the electromagnetic sensor was located in a position characterizing a displacement phase of the tissue or organ. A third method does not capture an X-ray projection for the reconstruction if the electromagnetic sensor is located in a position characterizing a displacement phase.

摘要： The invention relates to an operating method for an imaging system for the time-resolved mapping of an iteratively moving examination object. First recordings of the object are generated by the imaging system from various angles while simultaneously recording a phase signal. Multiple static 3D-image data sets corresponding to a sequence of defined phases are reconstructed from the first recordings. Three-dimensional motion fields are calculated from the 3D-image data sets, by which two 3D-image data sets are mapped onto one another. Second recordings of the object are generated by the imaging system from various angles while simultaneously recording a phase signal. 3D-image data sets from the second recordings in a previously determined reference phase of the phase signal using the motion fields is generated which is a sequence of motion-compensated 3D-image data sets.

摘要： A control device pivots an X-ray arrangement repeatedly between two final angular positions about a pivot axis. Projections of an object arranged in the region of the pivot axis and moving iteratively are detected at a plurality of angular positions and supplied to the control device. The control device also receives a phase position referring to the object and assigns the phase position to each projection. A computer selects one or more projections whose phase position corresponds at least approximately to a reconstruction phase position. If the computer has selected one projection for an angular position, it determines this projection as a reconstruction projection. If the computer has selected a plurality of projections for an angular position, it detects the reconstruction projection using these projections. The computer then detects a three-dimensional reconstruction of the object based on the reconstruction projection.
