Abstract
In the analyzed cardiac CT algorithm applied when comparing the MAR self-made metal artifact reduction in pacemaker inserted phantom degree. Result of comparing the energy value by CT showed a decrease in the CT value in the case of BKG 40 KeV in WSA maximum decreased to 663.2% in the case of 140 KeV BHA were increased a maximum of 56.2%. In addition, the maximum was decreased by approximately 145% based on a 70 KeV artifacts in CT value comparison by type WSA, BHA was to increase up to approximately 46.38%. MAR Algorithm is believed to provide a more quality cardiac CT image if the energy changes, or have the effect that by type and irrespective of reduced metal artifacts occurrence of artifacts applied to the pacemaker when tracking a heart CT scan after inserting MAR algorithm.
