摘要： An interpolation of data values is performed during the acquisition of a 3D image dataset which is free of traces of a metal object imaged in the underlying 2D image datasets. A target function is defined into which data values of the 3D image dataset that are dependent on said substitute data values are incorporated following preprocessing. The substitute data values are then varied iteratively until the value of the target function satisfies a predetermined criterion. Residual artifacts that still persist following the interpolation can thus be effectively reduced.

摘要： A method is provided for supplying a 3D X-ray image data record for a moving object. The said object contains highly X-ray radiation-absorbent material. A correction is made in respect of the highly absorbent material in 2D forward projections obtained from a 3D-X-ray image data record. The forward projections are calculated using 3D motion fields, which are derived from original 2D X-ray image data records.

摘要： The invention relates to a method and a device for increasing contrast in medical images generated by an imaging system featuring an x-ray source and a detector. The detector detects x-rays of the x-ray source and converts image signals from the x-rays. The image signals are transferred to a control and processing unit for processing. Deconvolution of the image signals is carried out by application of an inverse modulation transfer function modified by a regularization. At least a volume image can be reconstructed from the deconvolved image signals.

摘要： A method is disclosed for reconstruction of image data of an object under examination from measurement data, with the measurement data having been recorded during a rotating movement of a radiation source of a computed tomography system around the object under examination. The radiation source emits focal and extra-focal radiation. In at least one embodiment of the method, the image data is determined from the measurement data by use of an iterative algorithm. A variable is used in the iterative algorithm which contains a distribution of the extra-focal radiation.

摘要： An apparatus for localizing a focal lesion in a biological tissue section applies electrical excitation signals to the tissue section and measures electrical response signals at a number of measurement locations on a surface of the tissue section that arise there due to the excitation signals. A computer reconstructs a distribution of electrical dipole moments from the response signals, this distribution of dipole moments overall best reproducing the response signals, and supplies the 3D spatial position of the distribution as an output.

摘要： A method is claimed for correcting truncation artifacts in a tomography method, wherein internal checkpoints having a low level of attenuation are selected within the projection image and external checkpoints are defined by extrapolation based on the internal checkpoints. An adaptation function is then tailored to the internal checkpoints and the external checkpoints. This allows truncation artifacts to be effectively suppressed during the reconstruction of sectional images.
