Method for post- reconstructive correction of images of a computer tomograph |
摘要 |
The present invention relates to a method for correction of images recorded by a computer tomograph in which, from projection data of the computer tomograph a 2D or 3D image is reconstructed and the image is corrected by adding it to a correction image. The outstanding feature of the method is that the correction image is computed from image data of the image reduced in its resolution and number and/or from projection data reduced in its resolution and number. The present method allows the computation of the correction image to be reduced to a fraction of the computation requirements for the standard reconstruction of the 2D or 3D images.
