PROBLEM TO BE SOLVED: To provide high-quality coronary CT images without regard to heartbeats. SOLUTION: A coronary imaging method, for reconstructing a CT image of the coronary artery by extracting scan data in a given heart phase according to an ECG waveform detected along with a heart scan, includes the step of reconstructing CT images in a plurality of heart phases (α1 toα3) for each of the slice faces (z1 to z3) of the heart and displaying the images in arrays on a screen, the step of selecting at least one coronary CT image (e.g. coronary artery A1 in the array z2,α2) in the arrays being displayed, the step of extracting another coronary CT image with the same or similar feature to the selected coronary CT image from the arrays on the slice faces (z1, z3, etc.), in front of and behind the slice face of the selected image, and the step of displaying the selected and extracted coronary CT images (e.g. A1 in the array z2,α2, A1 in the array z1,α1, and A1 in the array z3,α3) in a predetermined format on the screen.
