1. An ultrasound diagnostic apparatus comprising:
an ultrasound probe;
a monitor;
a processor configured to:
acquire ultrasound images of a plurality of frames in which a cross section of a blood vessel of a subject is consecutively imaged while the ultrasound probe is moved,
detect an insertion object inserted into the subject, from each of the ultrasound images of the plurality of frames,
sequentially detect tilt angles of the ultrasound probe,
superimpose at least one geometric figure representing at least one position of the insertion object detected only at a tilt angle of the ultrasound probe within a predetermined angle range among multiple positions of the insertion object detected from the ultrasound images of the plurality of frames, on the ultrasound image of a latest frame among the ultrasound images of the plurality of frames, where the predetermined angle range has a central angle, and the central angle is set based on a traveling direction of the blood vessel, and
display the at least one geometric figure on the monitor.
