摘要： A method and system for autoregressive model based pigtail catheter motion prediction in a fluoroscopic image sequence is disclosed. Parameters of an autoregressive model are estimated based on observed pigtail catheter tip positions in a plurality of previous frames of a fluoroscopic image sequence. A pigtail catheter tip position in a current frame of the fluoroscopic image sequence is predicted using the fitted autoregressive model. The predicted pigtail catheter tip position can be used to constrain pigtail catheter tip detection in the current frame. The predicted pigtail catheter tip position may also be used to predict abnormal motion in the fluoroscopic image sequence.

摘要： Registration of preoperatively acquired MRI images of soft parts to intraoperatively acquired X-ray images of soft parts is not possible. The invention shows a way of nevertheless using such preoperatively acquired images for superimposition with 2D projections of the soft parts, taking an indirect route via 3D/3D registration of images of the spinal column. For this purpose, 3D image data sets of the spinal column must be obtained separately on the one hand using MRI and on the other using the X-ray imaging system so that the 3D/3D registration produces a mapping rule which then also applies to the preoperatively acquired images of the soft part if the soft part images and the spinal images are acquired without intervening change in the patient position in the MRI scanner.

摘要： The invention relates to a method and an apparatus for setting a dynamically adjustable position of an imaging system for providing an optimum view onto a moving object during a medical intervention. A time-resolved at least three-dimensional data record of the moving object is generated. A position of the imaging system for each period of time is determined from the time-resolved data record from which the optimum view onto a structure of interest of the moving object is produced and automatically setting a calculated position of the imaging system in real-time so that the optimum view onto the structure of interest can be shown at any time. Optionally prior to determining the position of the imaging system, a structure of interest of the moving object can be segmented with this structure being segmented for each period of time from the time-resolved data record.

摘要： A method for producing a 3D image dataset of an object with an imaging system having an x-ray source and an x-ray detector is provided. A series of two-dimensional arrays of cone beam data from the detector is acquired while the source moves along a substantially planar trajectory around the object. The trajectory is described by a series of source points serially numbered by a counter parameter. The cone beam data is differentiated with respect to the counter parameter at a fixed ray direction to produce a derivative of the cone beam data. The derivative is filtered with a Hilbert-like filter to produce filtered cone beam data. The acquired or the filtered cone beam data is multiplied with a redundancy weighting function. The cone beam data is back-projected to reconstruct a 3D image dataset.

摘要： A method for correcting truncated projection data of a rotation for a reconstruction technique for computed tomography scans with truncated projection data in the computed tomography images produced by a C-arm is proposed. At least one truncated projection is recorded. The truncated portions prior to acquisition of the rotation for the at least one truncated projection is captured. The truncated projection and the truncated portions are assembled into at least one complete projection. Truncated projection data is acquired during the rotation. The truncated data is estimated based on a model of the patient geometry from the at least one complete projection. A reconstruction technique is performed on the basis of the acquired and the estimated data.

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： 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.
