Method for reconstructing image data of investigation object from CT-system in medical application, involves using iterative algorithm for computing difference between first image data and second image data

摘要

The method involves detecting measurement data (p) between a radiation source (C2, C4) of a computer tomography (CT) system (C1) and an investigation object during movement. Movement of the measurement data from first image data to second image data is determined. An iterative algorithm is used to compute difference between the first image data and the second image data. A terminal is moved based on the computed image data and enhanced image data information to determine movement artifacts. Independent claims are also included for the following: (1) a computing unit (2) a CT-system (3) a computer program comprising a set of instructions for reconstructing image data (4) a data carrier.
