Abstract

An X-ray diagnostic apparatus according to an embodiment includes a support mechanism, bed, dosimeter, dose decision unit, dose distribution generation unit and display unit. The support mechanism movably supports an X-ray tube generating X-rays over a plurality of times in a predetermined period and an X-ray detector detecting X-rays transmitted through an object. The bed includes a top on which the object is placed. The dosimeter measures a total dose over the period. The dose decision unit decides doses respectively corresponding to times of generation of the X-rays in the period based on the total dose and an X-ray irradiation condition. The dose distribution generation unit generates a dose distribution based on a position of the support mechanism, a position of the bed, and the doses. The display unit displays the dose distribution.
