摘要： A multi-element ultrasonic transducer in which elements are arrayed and in which a plate-shaped piezoelectric material has its one face formed with a uniform electrode and its other face formed alternately with electrodes corresponding to the respective elements and electrodes for separating the elements. These electrodes for the element separation are connected the uniform electrode opposed thereto and is fed with a ground potential. On the other hand, the electrodes corresponding to the respective elements are fed individually with transmitting and receiving signals independently of the elements so that the electronic scanning or focusing operations can be achieved.

摘要： An ultrasonic flow mapping apparatus transmits and reflects waves from sampling points on a two-dimensional cross-section. The waves are detected while transmitting repeatedly ultrasonic pulses. The phase shifts of different reflected waves are calculated, and displayed in color to show a distribution of blood flow velocity. Artifact due to reflected waves from body organs, which remain even by using MTI filters, is detected from phase signals, which have not passed through the MTI filters, and the artifact is removed by lowering display brightness for a sampling point corresponding to a relevant detection output.

摘要： In an ultrasonic imaging apparatus, when a sampling time space determined corresponding to the respective phases of receiving signals from transducer elements adjacent to each other is shorter than the settling time of sample and hold circuits, these receiving signals are sampled at the same time. Noise is prevented from being mixed with the sample and hold values of these signals.

摘要： A pulsating sound wave beam is transmitted into an object using an array-type ultrasonic wave transducer which consists of a plurality of elements; the reflected sound waves are received using said transducer while electronically focusing the reflected sound waves depending upon an estimated speed of sound in the object, and the beam width of sound waves is measured repeatedly near a particular reflector while successively changing the estimated speed of sound. The estimated speed of sound of when the beam width is minimal is the mean speed of sound of the object in practice, and the beam width at that moment serves as an indication of acoustical homogeneity of the object.

摘要： An ultrasonic diagnosis apparatus for obtaining an ultrasonic echo image upon transmission/reception of a focussed ultrasonic beam by using an ultrasonic probe having curved array transducer elements disposed in a convexity. As the delay distribution data to be used for focussing respective transducer elements, a plurality of sets of delay distribution data, each set corresponding to a particular thickness of a fat layer under a skin of a specimen, are stored in a memory. In imaging the specimen, a set of the plurality of sets of delay distribution data is selected and read in accordance with the thickness of the fat layer of the specimen to control the delay distribution of a transmission or reception signal for respective transducer elements to thereby eliminate focussing errors to be caused by the concave lens effect of the fat layer.
