摘要：
An X-ray diagnostic apparatus according to an embodiment controls the imaging system in order to generate an X-ray image in which an imaging center line connecting a focus of an X-ray tube and a center position of an X-ray detection surface has a tilt angle of smaller than 90° with respect to a guideline connecting an input insertion target position and an input arrival target position； extracts from the image, a region of the needle inserted in an object； specifies an apparent length of the needle based on the region of the needle extracted from the X-ray image having the tilt angle of smaller than 90°； calculates an estimated insertion length of the needle inserted in the object based on the apparent length of the needle and the tilt angle； and notifies a user of information for assisting an insertion operation of the needle based on the estimated length.
