Method for reducing artifact of computed tomographic image data of e.g. dual source computed tomographic scan, involves reconstructing final computed tomographic data from final projection data set |
摘要 |
<p>The method involves scanning a testing object i.e. patient (7), with two X-ray sources (2, 4). Input projection data sets are combined to a common projection data set. One of the projection data sets and the common projection data set are segmented into two separated projection data sets with different spatial frequency bands. A final projection data set is generated from a low-frequency input projection data set and from high frequency regulated common projection data set. A final computed tomographic data is reconstructed from the final projection data set. An independent claim is also included for a computed tomographic system with a computer and a memory for storing of program code for performing a method for reducing artifact of computed tomographic data from dual or multi source scan.</p> |
