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).

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： A system for analyzing an echo image containing a contour of an organ with reduced manual operation is provided. The echo image is first obtained. A user manually sets, say, four points as known or initial points such that two of the known points provide a width of the contour and the other two of the known points provide a height of the contour. A search region including a connecting line segment connecting each pair of adjacent ones of the known points is set on the contour. A search line segment that originates from a point bisecting the connecting line segment of the search region and reaches an end of the search region is set. Each search line segment is sought for a contour point constituting the contour. A contour is formed by connecting the contour points on the search line segments. Three points may be set as the initial points such that two of the initial points provide a width of the contour and the other one is on top of the contour.
