Method for movement correction of three dimensional digital subtraction angiography, during visualization of e.g. blood vessel tree in heart of human body, involves producing subtracted volume that is reduced at subtraction artifacts

摘要

The method involves implementing movement correction by two dimensional or three dimensional registration (27) and subtraction of two-dimensional image data sets, which comprise mask image data set and filling image data set. The mask image data set and the filling image data set are subtracted from each other. Registration process is applied for registration of image data sets. The process is based on additional two-dimensional image data sets so that subtracted volume is produced, where the subtracted volume is reduced at subtraction artifacts. The volume is represented using a display unit. An independent claim is also included for a device for movement correction of the three dimensional digital subtraction angiography.
