摘要： A computer receives a plurality of two-dimensional fluoroscopy images of an examination object, capture time points and projection parameters and combines the images into image groups. Each image group contains all the images, the capture time point of which is between a minimum and a maximum time point specific to the respective image group. When the image groups are sorted by ascending minimum time points, the corresponding maximum time points form a strictly monotonously ascending order. The respective minimum and maximum time points are determined so that the computer reconstructs a three-dimensional object reconstruction of the examination object based on the images assigned to the respective image group. A respective two-dimensional reconstruction display is determined by the respective three-dimensional object reconstruction and outputted to a user in a coding specific to the respective image group by a display device.

摘要： It is possible that at a predetermined position of the imaging components of a radiographic imaging system the object is not fully viewed. The object can be a calibration phantom, which means that it is not possible to directly determine an imaging rule with the aid of the calibration phantom at this position of the imaging components. According to the invention, an imaging of the calibration phantom at a different position takes place and an imaging rule for this position is determined. This is then converted, provided a movement parameter is known which describes the movement from the position with the record of the calibration phantom to a different position. The imaging rule obtained in this way can be further improved, e.g. with the aid of a recording of the calibration phantom from the position in question, including if the calibration phantom is not completely imaged.

摘要： Disclosed herein is a method, and system (1) for implementing same, 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. 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 obtained by recording a first image of the series recordings and then registering it or by calculating it. Each further image of the series recordings is registered immediately after recording to obtain the current spatial position of the examination area. Differences in spatial position are compensated for at least approximately by changing geometric relationships of the imaging system (1).

摘要： A method and apparatus for motion correction of medical image data of a patient are provided. Medical image data is obtained in a tomographic image recording process by back-projection from a number of projection images. The position of a magnetic location sensor, which is arranged on a medical implant inserted into a patient is also determined as a function of time while the projection images are being recorded, by means of an electromagnetic location system and the position is taken into account in the back-projection of the projection images for motion correction purposes.

摘要： For detecting the relative location of a laser or laser fan beam relative to the x-ray geometry of an x-ray device, a method for calibrating the position of the laser fan beam generated by a laser in relation to the projection geometry of the x-ray device is proposed. The x-ray device comprises an x-ray imaging system featuring an x-ray source and an x-ray detector. The x-ray source, the x-ray detector, the laser, and an imaging facility are arranged on a support. An optical x-ray calibration phantom is used for the calibration. The position of the imaging facility relative to the projection geometry is determined. The position of the laser fan beam relative to the imaging facility is determined. The position of the laser fan beam relative to the projection geometry is reconstructed.

摘要： The present invention relates to a method for the registration and superimposition of image data when taking serial radiographs in medical imaging, wherein a plurality of image data sets for a region of a patient (17) that is being investigated are constructed at time intervals using an imaging system (1) and are referenced with a first image data set for the region that is being investigated that was constructed previously using said imaging system (1). In the above method, a location system (2) is used during the production of serial radiographs constantly, or at least at a respective proximity in time to the construction of individual data sets, to determine a current spatial position of the region being investigated in a reference system that is firmly connected to the imaging system (1), whereby in the construction of the first image data set, a first spatial position of the region that is being investigated is recorded. In the construction of some or all further image data sets, the respective current spatial position of the region that is being investigated is determined and an image content of each first image data set is geometrically adapted on the basis of the difference between the first and the current spatial position, such that compensation is made for a different spatial position of the region that is being investigated. The geometrically adapted first image data set or an image data set derived therefrom, or an image data set that is positionally connected thereto by registration is then displayed superimposed with the respective further image data set.
