Ultrasound diagnostic apparatus and control method of ultrasound diagnostic apparatus

An ultrasound diagnostic apparatus comprising:

• an ultrasound probe;
• and
• an apparatus main body wirelessly connected to the ultrasound probe,
• wherein the ultrasound probe includes
• a probe side processor, and
• a probe side communication circuit,
• the probe side processor is configured to generate ultrasound images at a constant frame rate, to assign sequence numbers to the ultrasound images generated at the constant frame rate in an order of generation of the ultrasound images, and to adjust a frame interval of the ultrasound image transmitted to the apparatus main body by skipping transmission of some frames of the ultrasound image to the apparatus main body per unit time in accordance with a transmission rate of the ultrasound image,
• wherein the probe side communication circuit transmits the ultrasound image with the adjusted frame interval to the apparatus main body via wireless communication, and
• the apparatus main body includes
• a main body side communication circuit that receives the ultrasound image via the wireless communication from the ultrasound probe,
• a main body side processor, and
• a monitor, and
• the main body side processor is configured to calculate a second number of frames of the ultrasound image skipped from transmission to the apparatus main body per the unit time in the ultrasound probe by determining a frame of the ultrasound image from which the sequence number is missing among the ultrasound images received by the main body side communication circuit is the frame of the ultrasound image skipped from transmission to the apparatus main body, and to determine a communication quality of the wireless communication on the basis of both a ratio of a first number of frames of the ultrasound image received from the ultrasound probe per the unit time to the calculated second number of frames and a variation in frame intervals of the ultrasound image received from the ultrasound probe per the unit time, and to display information on the communication quality on the monitor.
