摘要： First 1-sound-line received signals are successively generated from an output signal of a transducer. One is selected from among the generated first 1-sound-line received signals as a 1-sound-line received signal of interest. Second 1-sound-line received signals are selected from among the generated first 1-sound-line received signals. The second 1-sound-line received signals include a 1 -sound-line received signal preceding the 1-sound-line received signal of interest and also a 1-sound-line received signal following the 1-sound-line received signal of interest. The second 1-sound-line received signals are averaged into a mean 1-sound-line received signal which corresponds to an undesired multiple-echo signal. The mean 1-sound-line received signal is subtracted from the 1-sound-line received signal of interest to remove the undesired multiple-echo signal from the 1-sound-line received signal of interest.

摘要： There is provided an ultrasonic Doppler blood-flow meter which can suppress the occurrence of unwanted frequency components by suppressing the jump of signal to thereby produce images of high quality A DC feedback circuit is provided which negatively feeds back a Doppler deviated signal produced from an integrator to the input thereof. The feedback amount of the DC feedback circuit is changed in synchronism with the timing for switching between the B-mode transmission/reception sequence and the Doppler mode sequence to prevent a jump of a signal at the commencement of the Doppler mode. The feedback amount of the DC feedback circuit is made to be different for the gate moving sequence and the Doppler mode sequence, thereby preventing a jump of a transient signal due to a discontinuous input signal at the commencement of the Doppler mode.

摘要： An ultrasonic diagnostic apparatus includes a transducer array 1 in which a plurality of transducers for transmitting an ultrasonic wave to a subject and receiving a reflected wave therefrom are arrayed, and delay addition units 4 to 9 for performing parallel reception by adding a delay time to signals from the transducer array. The apparatus further includes a deflection angle control unit 14 that performs control so that an angle formed between a plurality of directions of reception directivities in the parallel reception decreases as a deflection angle of a transmission beam transmitted from the transducer array increases. Thus, the ultrasonic diagnostic apparatus that keeps relative sensitivities in the parallel reception uniform irrespective of the deflection angle of the ultrasonic transmission beam is provided.

摘要： A blood pressure determining apparatus is provided which applies oscillations to the blood vessel of a subject through an exciter to determine the blood pressure based on the frequency of the oscillations propagated through the blood vessel measured by an oscillation sensor. The apparatus monitors an output of the oscillation sensor when the exciter applies no oscillation to the subject to determine the power spectrum of noise signals contained in the output and sets the frequency of oscillations to be applied to the blood vessel to any value within a band of the power spectrum in which the power of noise is small. This enables the blood pressure to be determined without influence of any electric disturbances from peripheral devices.
