Claim One:
1. Examination apparatus for reconstruction of the coronary arteries, the examination apparatus comprising: at least one X-ray image acquisition device ( 10 ); a calculation unit ( 18 ); an electrocardiogram device; and a display device ( 20 ); wherein the electrocardiogram device is adapted for providing a gating signal ( 132 ); wherein the image acquisition device is of a C-type and adapted for acquiring a first gated X-ray image sequence ( 34 ; 134 ) of one of the left and right branches of the coronary arteries with injected contrast agent into the one of the left or right branches of the coronary arteries and for acquiring a second gated X-ray image sequence ( 36 ; 136 ) of the other branch of the coronary arteries with injected contrast agent into said other branch; wherein the calculation unit ( 18 ) is adapted for performing gated reconstructions ( 38 ; 138 ) of the left and the right coronary artery and for generating volume data ( 40 , 42 ; 140 , 142 ) of the coronary arteries; for temporal registration of the volume data of the coronary arteries; for spatial registration of the volume data of the coronary arteries; and for combining ( 54 ) the volume data of the coronary arteries and generating a combined coronary artery tree volume data set ( 52 ); and wherein the display device is adapted for visualizing ( 56 ) the combined coronary tree volume data set image.
