摘要： An ultrasonic probe has an elongated form with an end. A transducer element array is disposed in the probe for emitting ultrasonic wave frontward with respect to the end of the probe and receiving echo ultrasonic waves. The transducer element array converts the received echo ultrasonic waves into corresponding electric echo signals. The electric echo signals are processed according to a predetermined aperture synthesis technique, and thereby an image signal is generated on the basis of the electric echo signals. An image of a region in front of the end of the probe is reproduced in response to the image signal.

摘要： An ultrasonic Doppler imaging apparatus emits ultrasonic pulse waves to an object body under test and provides information on blood flow in the body based on Doppler shifts of ultrasonic waves reflected back from the object body. The ultrasonic pulse waves emitted by a probe (1) to the object body undergo Doppler shifts by being reflected by the blood stream, and the reflected ultrasonic waves received by the probe are decomposed with an A/D converter (8) in synchronism with emission. The decomposed data are transformed into complex Doppler data through a quadrature addition/subtraction by quadrature addition/subtraction means (9). The complex Doppler data is subjected to frequency analysis through the correlative computation or the like, and resulting data is stored in a frame memory (16) and displayed. The apparatus is capable of measuring the Doppler shift frequency accurately.

摘要： An ultrasonic diagnostic system includes a transducer. A first electric drive signal is fed to the transducer. A second electric drive signal is fed to the transducer at a time different from a time of the feed of the first electric drive signal thereto. The second electric drive signal has a waveform different from a waveform of the first electric drive signal. A first received signal is derived from an output signal of the transducer. The first received signal represents ultrasonic echoes related to an ultrasonic beam caused by the transducer in response to the first electric drive signal. A second received signal is derived from the output signal of the transducer. The second received signal represents ultrasonic echoes related to an ultrasonic beam caused by the transducer in response to the second electric drive signal. The first received signal is subjected to a waveform equalizing process, thereby being converted into a third received signal having a waveform corresponding to a waveform of the second received signal. A calculator operates for calculating a difference between the second received signal and the third received signal, and generating a signal representing the calculated difference.

摘要： In an ultrasonic diagnostic equipment for performing synthetic aperture, deterioration of picture quality produced by the movement of an object is prevented, thereby to provide an excellent image. Arrayed piezoelectric transducers (1) are driven by a transmitting circuit (2) so as to transmit ultrasonic waves into a body, and, among echoes received by piezoelectric transducers (T1 ∼ T8), first the signals of the piezoelectric transducers (T3 ∼ T6) are selected by (SW3 ∼ SW6), amplified appropriately by amplifiers (7 ∼ 10) and converted into digital signals by (A/D11 ∼ A/D14), added with delay by a beam former (15) thereafter, and stored in a memory (16). Similarly, the ultrasonic waves are transmitted again, signals of the piezoelectric transducers (T1, T2, T7, T8) are selected by the (SW3 ∼ SW6), applied with similar signal processing in the amplifiers (7 ∼ 10), (A/D11 ∼ A/D14) and the beam former 15, and added to signals added with delay of the piezoelectric transducers (T3 ∼ T6) stored in a memory 16 by an adder (17). The added signals are displayed on a display unit (20) after applying signal processing such as detection in a signal processing portion (19).
