REFERENCE IMAGE SEQUENCE RECORDING FOR INTERFERENCE SIGNAL ELIMINATION AND FILTERING IN MEDICAL IMAGE SEQUENCES

摘要

When taking X-ray image sequences in the heart area, the relevant objects in the image sequence are characterized by rhythmic movements determined by the heart activity. An effective interference filtering process for such image sequences uses this preliminary knowledge about these movements whose repetition is synchronous with the pulse of the patient. This process may generally be used to filter out interferences from other medical image sequences as well, in which movements synchronous with the heartbeat of the patient are detected.
