Ultrasound diagnostic system

An ultrasound diagnostic system comprising:

• an ultrasonic probe having a plurality of transducers and configured to obtain a plurality of pieces of ultrasound image data of a subject, the plurality of transducers being arranged in a first direction and configured to transmit ultrasonic waves toward the subject and receive ultrasonic waves reflected from the subject;
• a moving mechanism configured to move the ultrasonic probe in the first direction and in a second direction perpendicular to the first direction;
• and
• a controller including a processor being configured to perform a process including,
• causing the moving mechanism to move the ultrasonic probe based on a position of an image of a blood vessel to be observed of the subject in an ultrasound image indicated by a corresponding piece of the plurality of ultrasound image data, and
• generating blood vessel map data indicating information related to the blood vessel to be observed by referring to an image data storage in which the plurality of pieces of ultrasound image data are stored in association with respective amounts of movement in the first direction and in the second direction.
