Classification: CPC A  G | IPC A

Claim 0:
1. An ultrasound diagnostic apparatus comprising:
an ultrasound probe including a transducer array and a diagnostic apparatus main body including a monitor, where the ultrasound probe and the diagnostic apparatus main body are wirelessly connected to each other; and a B-mode and a pulsed wave Doppler 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 B-mode image based on the sound ray signal generated by the transmission and reception circuit,
set a Doppler gate on the B-mode image,
set a number of a plurality of sampling points within the Doppler gate on the B-mode image,
generate complex baseband signals at the plurality of sampling points based on the sound ray signal generated by the transmission and reception circuit,
average the complex baseband signals at the plurality of sampling points to acquire average complex baseband signals,

where a number of the plurality of sampling points in the Doppler gate is set such that a wireless transmission data amount per unit time required for wirelessly transmitting the complex baseband signals at the plurality of sampling points without averaging exceeds the wirelessly transmittable data amount and a wireless transmission data amount per unit time required for wirelessly transmitting the average complex baseband signals is equal to or less than the wirelessly transmittable data amount, and
a probe-side wireless communication circuit configured to wirelessly transmit the average complex baseband signals acquired by the first processor, and

the diagnostic apparatus main body includes
a main body-side wireless communication circuit configured to receive the average complex baseband signals wirelessly transmitted from the probe-side wireless communication circuit, and
a second processor configured to
perform a frequency analysis on the average complex baseband signals received by the main body-side wireless communication circuit to generate a Doppler image, and
display the Doppler image on the monitor.
