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： In accordance with the principles of the present invention, advantage is taken by the inventors of the fact that the speed of operation of the digital hardware in a digital beamformer can be reduced by providing, for example, multiple phases of the data signals and then processing the multi-phase data in N parallel summing paths. An interpolation-decimation filter receives the multi-phase data from the N parallel summing paths and provides at its output a signal having a reduced data rate (1/N). In accordance with this technique, the speed of operation of the individual digital circuits for forming the required beamforming delays is not increased as compared to conventional post-beamforming interpolation schemes, so that hereby the effective data rate is increased by a factor N and results in a decrease of the delay quantization error by a factor N. In accordance with the principles of the invention, the interpolation-decimation filter is incorporated into the beamformer at a most advantageous place. That is, it is incorporated into the beamformer processing after partial beamforming of a group of receive channels and before formation of the final beam. This approach allows the final beamforming to be simple and performed at a relatively low data rate and allows the higher rate signal processing to be confined to circuitry which may advantageously be on a single type of integrated circuit which is repetitively used in the beamformer.

摘要： An ultrasound diagnostic apparatus includes a linear array of piezoelectric transducers or plates with a width-to-thickness ratio of less than 0.8 and a control circuit which includes a transmitter and a receiver. The transmitter comprises a plurality of transmitting channels each including a local oscillator for generating an ultrasonic pulse in response to a clock signal. The plurality of such ultrasonic pulses are applied through a switching network to a selected group of successively arranged piezoelectric transducers to transmit a beam of ultrasonic energy into a human body. Each of the ultrasonic pulses is phase shifted and amplitude modulated with respect to the ultrasonic pulses of the other transmitting channels to provide phase and amplitude taper which results in a narrow width beam through the depth of the body. The ultrasonic energy returned from discontinuities between different tissues is detected by the activated transducers and applied through the switching network to the receiver in which each of the return signals is phase shifted and amplitude modulated with respect to the other signals to provide an output signal which is displayed on a cathode ray tube screen.
