Ultrasound diagnostic apparatus and control method of ultrasound diagnostic apparatus

An ultrasound diagnostic apparatus comprising:

• an ultrasound probe including a transducer array and an ultrasound diagnostic apparatus main body including a monitor, the ultrasound probe and the ultrasound diagnostic apparatus main body being wirelessly connected to each other,
• wherein the ultrasound diagnostic apparatus is configured for a color flow mode,
• wherein the ultrasound probe includes
• a transmission and reception circuit configured to
• cause the transducer array to transmit an ultrasonic pulse toward a subject, and
• perform reception focusing processing on a reception signal output from the transducer array that has received an ultrasound echo from the subject to generate a sound ray signal,
• a first processor configured to
• generate a complex baseband signal based on the sound ray signal generated by the transmission and reception circuit,
• perform high-pass processing and autocorrelation analysis processing on the complex baseband signal, and
• generate phase data including only phase information without including amplitude information based on the complex baseband signal subjected to the high-pass processing and the autocorrelation analysis processing, and
• a probe-side wireless communication circuit that wirelessly transmits the phase data including only phase information without including amplitude information generated by the first processor, and
• the ultrasound diagnostic apparatus main body includes
• a main body-side wireless communication circuit that receives the phase data wirelessly transmitted from the probe-side wireless communication circuit of the ultrasound probe, and
• a second processor configured to
• generate a complex signal including only phase information without including amplitude information based on the phase data received by the main body-side wireless communication circuit,
• generate a color flow image based on the complex signal while ensuring an accuracy of the color flow image, and
• display the color flow image on the monitor.
