<p>In forming the sending beams of B mode and Doppler mode using a common beam-forming data, the ultrasonic diagnosing apparatus of the invention can adjust the size of sample volume in either the direction of depth or azimuth and further can reduce the quantity of ultrasonic wave irradiating the sample to be inspected. In the case of the B mode operation, a fully sharply focused ultrasonic wave beam is sent and received based on the beam-forming data for B mode and in the case of the Doppler mode operation, a fuzzily focused ultrasonic wave beam as expected is sent and received based on the beam-forming data obtained by modifying the beam-forming data for B mode.</p> |
