Ultrasound diagnostic apparatus and control method of ultrasound diagnostic apparatus

An ultrasound diagnostic apparatus that displays an insertion object to be inserted into a blood vessel of a subject on an ultrasound image, the ultrasound diagnostic apparatus comprising:

• a transducer array;
• a transmission and reception circuit configured to
• cause the transducer array to transmit an ultrasound beam toward the subject, and
• process a reception signal output from the transducer array that has received an ultrasound echo from the subject to generate a sound ray signal;
• a processor configured to
• generate the ultrasound image based on the sound ray signal generated by the transmission and reception circuit,
• detect the blood vessel and the insertion object by analyzing the ultrasound image, and
• control the transmission and reception circuit such that a frame rate at which the ultrasound image is generated is adjusted, based on a relative positional relationship between the blood vessel and the insertion object which are detected.
