An X-ray computed tomographic apparatus wherein image data are reconstructed on the basis of a plurality of data segments which extend over a plurality of heart beats extracted from data obtained by scanning a patient with X-rays under helical scan, comprising:
a generation device (41) which is configured to generate on the basis of a heart rate of the patient, a plurality of temporal resolutions which correspond respectively to a plurality of helical pitches and/or rotational speeds concerning the helical scan;
a screen building device (43) which is configured to build a scan plan screen that contains the plurality of the helical pitches and/or rotational speeds, and the plurality of generated temporal resolution, and which contains a graph which expresses a temporal change of the temporal resolution versus a temporal change of the heart rate of the patient; and
a display device (38) which displays the scan plan screen.
