    摘要: A method for calculating perfusion data, such as blood volume or blood flow from 2-D angiography data or DSA sequences, is proposed. An angiography scene is recorded using specific acquisition parameters to generate the 2-D angiography data or DSA sequences with administration of contrast agent based on a multiplicity of individual angiography images. A region of interest is defined suitable for comparison purposes. The volume segments are defined by the region of interest. The time/contrast curve is determined in the volume segments. Perfusion data for calculating the relative perfusion data is ascertained. The perfusion data is compared and the relative perfusion data is calculated. The calculated relative perfusion data is not specified in terms of absolute physical quantities, but is provided simply as ratios, such as left/right or before/after.

    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: The invention relates to a method for presenting interventional instruments in a 3D data set of an anatomy to be treated. A 3D data set of the anatomy is recorded before introduction of an interventional instrument. Once the interventional instrument has been applied, the spatial position of the instrument is determined by x-ray fluoroscopy from images created at two different angulations. A 3D model of the instrument is formed from the x-ray images. The 3D model of the instrument is fused with the 3D data set of the anatomy. A 3D hologram is reproduced from the fused 3D data set. The 3D hologram is repeatedly reproduced in real time to follow the application of the instrument in the presentation.
