摘要： Ultrasound imaging uses matrix arrays (100). A common design is used for an integrated circuit (140). The integrated circuit (140) is programmable so that the same design of integrated circuit (140) may be used with different types of arrays (100), such as matrix arrays (100) with different pitches. The design allows for one element (102) to connect with multiple, identical processing circuits (200) of the signal processor (140).

摘要： An ultrasound system with a matrix array (500) probe (10) operable in the biplane mode is used to assess stenosis of a blood vessel by simultaneously displaying two color Doppler biplane images (60a, 60b) of the vessel, one a longitudinal cross-sectional view (60a) and the other a transverse cross-sectional view (60b). The two image planes intersect along a Doppler beam line (68) used for PW Doppler. A sample volume graphic (SV) is positioned over the blood vessel at the peak velocity location in one image, then positioned over the blood vessel at the peak velocity location in the other image. As the sample volume location is moved in one image, the plane and/or sample volume location of the other image is adjusted correspondingly. Spectral Doppler data (62) is then acquired and displayed from the sample volume location.

摘要： An underwater detection apparatus (1, 1a) is provided. The underwater detection apparatus (1, 1a) includes a transmission transducer (10, 10a, 10b), a reception transducer (5, 5a), an attitude information receiver (14), a transmission circuit (18, 18a), and a reception circuit (4, 4a). The transmission transducer (10, 10a, 10b) includes a plurality of transmission elements (A, 32) configured to be fixed to a vessel (S), each transmission element (A, 32) extending in an oblique direction relative to a fore-aft direction of the vessel (S). The reception transducer (5, 5a) includes a plurality of reception elements (B). The attitude information receiver (14) acquires an attitude information of the vessel (S). The transmission circuit (18, 18a) drives the plurality of transmission elements (A, 32) based on the attitude information to make the transmission transducer (10, 10a, 10b) transmit a transmission wave in a given direction relative to the water surface. The reception circuit (4, 4a) obtains a reception signal from each of the plurality of reception elements (B) based on a reflection wave of the transmission wave, the reflection wave being received by the reception transducer (5, 5a).

摘要： Without using any approximated wave front propagation model, appropriate delay times are set for received signals to obtain phased signals for both the inside and outside of irradiation area of transmission beam.
A reception beamformer comprises a wave front propagation calculator 121 that obtains times until ultrasonic waves transmitted from a plurality of ultrasonic transducers arrive at a reception focus by calculation, and a delay time extractor 122 that calculates delay times for the reception focus on the basis of distribution of the arrival times of the ultrasonic waves for each of the plurality of the ultrasonic transducers obtained by the wave front propagation calculator 121. Therefore, even if the wave front that arrives at the reception focus has a complicated shape, it is not necessary to approximate the wave front, and phasing addition can be performed with appropriate delay times obtained from times until the ultrasonic waves arrive at the reception focus.
