An X-ray diagnostic device (1) according to an embodiment of the present invention is provided with: a profile measurement unit (25); a correction-factor identification unit (26); a DSA image correction unit (27); and a controller (34). The profile measurement unit (25) respectively measures profiles in 2 difference images of a head of a subject imaged from substantially identical directions at different imaging times, said profiles being related to contrast-medium concentration in blood-vessel-containing regions of interest respectively set in substantially identical positions. The correction-factor identification unit (26) identifies a correction factor such that two profiles respectively measured by the profile measurement unit (25) substantially correspond. The DSA image correction unit (27) corrects at least one of the 2 difference images on the basis of the identified correction factor. The controller (34) implements control such that information based upon the 2 difference images, at least one of which having been corrected by the DSA image correction unit (27), is displayed on a display (40). |
