摘要： There is described a method for correction of truncation artifacts in reconstructed tomographic images in a reconstruction method for tomographic images with truncated projection image data in the reconstructed tomographic images, in which divergent radiation is emitted from a radiographic source, an object to be examined is x-rayed with the divergent radiation in different projection directions, the radiation penetrating through the object to be examined is detected by a detector as projection images, with the data of the signal being arranged in a number of projection data rows and projection images detected by the detector being expanded line-by-line through extrapolation of the projection data rows. In this case the signal of a projection data row can be smoothed with a polynomial filter to reduce the noise component of the signal and the truncated proportion of the projection data row can be computed from the smoothed signal of the projection data row by means of an extrapolation method, with the extrapolation widths being derived from a number of rows.

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： The present invention relates to a method and also an imaging system to compensate for patient motion when recording a series of images in medical imaging, in which a number of images of an area under examination of a patient (17) are recorded at intervals with an imaging system (1) and are related to one another. With the method a localization system (2) is used as the series of images are being recorded to permanently or at a time close to the recording of the individual images, record a momentary spatial location of the area under examination in a reference system permanently linked to the imaging system (1), a first spatial location of the area under examination recorded close to the time of recording of a first image is stored, and a deviation of the images recorded momentarily in each case of the first spatial location is determined and by changing the geometrical circumstances of the imaging system (1) at a time to close the recording of the spatial location and/or through geometrical adaptation of an image content of an image just recorded, is at least approximately commentated for, so that the images show the area under examination in the same position and orientation. The method does not require any time-consuming interaction with the operator and is also suitable for compensating for larger movements of the patient.

摘要： The invention relates to a method for “truncation correction” in an x-ray system, i.e. a correction method during the reconstruction of projection images of an object recorded from different projection angles, if parts of the object do not lie in the field of view of each projection image. The surface of the object is thereby optically detected and used during the reconstruction of projection images to supplement the missing image data.
