Abstract: PROBLEM TO BE SOLVED: To correct ultrasound data.SOLUTION: The method for correcting ultrasound data includes: acquiring ultrasound data and transmitting it as received ultrasound signals along conductive pathways (202) of channels; determining a crosstalk signal that is generated in one or more of the channels by at least one of transmission of the received ultrasound signals along the channels or vibration of the transducer elements (104); and modifying subsequently acquired ultrasound signals that are transmitted along the channels based on the crosstalk signal.

Abstract: PROBLEM TO BE SOLVED: To isolate a short-circuited sensor cell for a highly reliable operation of a sensor array to neglect an influence onto imaging performance, as to an array of a finely machined ultrasonic transducer. SOLUTION: The present invention provides a device having a sensor array and a number of bus lines. Each of sensors is connected electrically to each of the bus lines and includes a large number of groups 58 of the finely machined sensor cells. The sensor cell groups for the specified sensor are electrically connected each other via the bus line with the sensor connected thereto, and each of the sensor cell groups includes the large number of finely machined sensor cells 2 connected electrically each other, and not disconnectable switchingly each other. The device further includes a means (for example, short-circuiting protection module including a fuse or current sensor circuit, and an electric isolation switch) for isolating anyone of the sensor cell groups from the related bus line, in response to the fact that the anyone out of the large number of finely machined sensor cells in anyone of the sensor cell groups is short-circuited to grounding.

Abstract: PROBLEM TO BE SOLVED: To image the flow of blood without using a contrast media by separating a basic wave signal when a wide band pulse is transmitted to a specified transmitting focal position a plurality of times, and filtering the separated basic wave signal by use of a high band pass wall filter. SOLUTION: In an ultrasonic wave B mode flow imaging system, an echo signal received by a transducer element 12 is supplied to each receiving channel 40 of a beam forming device. At this time, a receiving focusing time delay 42 is given to the receiving echo signal. With respect to each of N-stage transmitting firings focused to a specified transmitting focal position, the time-delayed received signal is added by a receiving adder 44, and then supplied to a wall filter 46. A filtering is performed during N transmitting firings, and the envelop of the signal between firings is formed by a detector 32 followed by post processing, and the scanning line is displayed on a monitor.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for improving medical ultrasonic images by data dependent filtering. SOLUTION: An amount called as a coherence degree C defined as the ratio of the amplitude A of coherently added reception signals and the amplitude B of non-coherently added reception signals is calculated 56 for the corner picture element of images. Coherence data are stored in buffer memories 58 and 60, and by optional selection, spatially filtered 62 and mapped 64. Amplitude data are simultaneously obtained and stored in the buffer memory. This system is selectively operated so as to display only coherence information, only amplitude information or the combination of the coherence and amplitude information.

Abstract: Procédés et systèmes (100) pour améliorer la corrélation d'ondes de déplacement à cisaillement. Le procédé comprend l'application d'une ou plusieurs impulsions de référence à une pluralité de zones cibles (102) afin de détecter des positions initiales correspondantes. Par ailleurs, une pluralité de segments d'impulsion de poussée sont appliqués à un ou plusieurs emplacements de poussée, un ou plusieurs paramètres correspondant à la pluralité de segments d'impulsion de poussée étant adaptés pour générer une onde de déplacement à cisaillement à forme d'onde voulue. De plus, une ou plusieurs impulsions de suivi peuvent être appliquées à la pluralité de zones cibles (102) pour détecter des déplacements d'au moins un sous-ensemble des zones cibles (102) en fonction du temps. En particulier, les déplacements sont déterminés en tant qu'échantillons temporels de l'onde de déplacement à cisaillement. Ensuite, un décalage de l'onde de déplacement à cisaillement détectée dans au moins deux zones cibles différentes (102) du sous-ensemble de la pluralité de zones cibles (102) est détecté.

Abstract: Es werden Verfahren und Systeme (100) zur Verbesserung der Korrelation von Scherverschiebungswellen vorgestellt. Das Verfahren umfasst die Abgabe von einem oder mehreren Bezugsimpulsen an eine Vielzahl von Zielbereichen (102), um die entsprechenden Ausgangspositionen zu erfassen. Es werden ferner eine Vielzahl von Druckimpulssegmenten an eine oder mehrere Druckstellen abgegeben, wobei ein oder mehrere Parameter, die der Vielzahl von Druckimpulssegmenten entsprechen, angepasst werden, um mindestens eine Scherverschiebungswelle mit einer gewünschten Wellenform zu erzeugen. Zusätzlich können ein oder mehrere Lokalisierungsimpulse an die Vielzahl von Zielbereichen (102) abgegeben werden, um Verschiebungen von mindestens einer Teilmenge der Zielbereiche (102) in Abhängigkeit von der Zeit zu erfassen. Die Verschiebungen werden insbesondere als Zeitabtastwerte der Scherverschiebungswelle ermittelt. Anschließend wird eine Verschiebung zwischen der Scherverschiebungswelle, die in wenigstens zwei unterschiedlichen Zielbereichen (102) in der Teilmenge der Vielzahl von Zielbereichen (102) erfasst wurde, ermittelt.

Abstract: The device has an array (10) of ultrasound transducer elements. A transmitter (12) forms a transmitting group for each of a number of sample volumes. A receiver (14) with several channels receives amplitude signals from the transducer elements. A device calculates an incoherence sum from the amplitude signals of the ultrasound echo from each sample volume. A display (20) has each pixel displaying the incoherent sum for one sample volume. Coherent values can also be calculated. An Independent claim is included for a method for coherent filtering of ultrasonic images
