Classification: CPC A | IPC A

Claim 13:
14. An X-ray diagnostic apparatus, comprising:
an X-ray source;
an X-ray detector;
an arm configured to support the X-ray source and the X-ray detector; and
processing circuitry configured to
acquire a three-dimensional image generated by imaging an object,
receive a designation of a target position of a blood vessel of the object in the three-dimensional image,
calculate an original orbit around the target position based on a location of the target position and a running direction of blood flow of the blood vessel corresponding to the target position in such a manner that the original orbit is within a plane orthogonal to the running direction of the blood vessel and including the target position,
perform positioning processing on the three-dimensional image in such a manner that the three-dimensional image positionally matches an X-ray image obtained by using the X-ray source and the X-ray detector to image the object,
convert the original orbit calculated for the three-dimensional image into a converted orbit for the X-ray source and the X-ray detector, and
cause the arm to rotate the X-ray source and the X-ray detector along the converted orbit in such a manner that a periphery of the target position is imaged.
