1. An ultrasound diagnostic apparatus comprising:
an ultrasound probe including a transducer array and a diagnostic apparatus main body including a monitor that are wirelessly connected; and a color flow mode,
wherein the ultrasound probe includes
a transmission and reception circuit that causes the transducer array to transmit an ultrasonic pulse toward a subject, and performs 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 probe-side processor that generates a B-mode image on the basis of the sound ray signal generated by the transmission and reception circuit and generates flow image information not imaged consisting of velocity data and at least one of dispersion data or power data on the basis of the sound ray signal generated by the transmission and reception circuit, and
a probe-side wireless communication circuit that wirelessly transmits the B-mode image and the flow image information generated by the probe-side processor, and
the diagnostic apparatus main body includes
a main body-side wireless communication circuit that receives the B-mode image and the flow image information wirelessly transmitted from the probe-side wireless communication circuit of the ultrasound probe, and
a main body-side processor that displays the B-mode image on the monitor and generates a color flow image on the basis of the flow image information received by the main body-side wireless communication circuit and displays the color flow image generated on the monitor,
wherein the probe-side processor is configured to
generate a complex baseband signal on the basis of the sound ray signal,
remove a clutter signal from the complex baseband signal,
perform autocorrelation processing on the complex baseband signal from which the clutter signal is removed to generate autocorrelation signals, and
generate the flow image information on the basis of the autocorrelation signals,
wherein the flow image information generated by the probe-side processor is wirelessly transmitted by the probe-side wireless communication circuit of the ultrasound probe to the diagnostic apparatus main body.
