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 ultrasound signal processor, respective received signals received at received signal processing units are sampled by a sampling clock of a frequency which is sufficiently higher than a Nyquist sampling frequency of an upper limit of a frequency band width for each of the received signals received at the received signal processing units so as to be digitized. Each of the digitized received signals is multiplied by a reference signal of a predetermined frequency to produce converted received signals in which the frequency of the digital received signal waveform is shifted, and converted signals are cumulated for a time which is longer than the sampling period. Each of the cumulated signals is processed by a clock frequency lower than the sampling clock in connection with an ultrasound beam in one direction, so that after one transmission operation of ultrasound, a plurality of ultrasound received beams are formed from the received signals received at the respective transducers.

摘要： This invention provides a technology that freely changes the frequency of a reference signal in a digital ultrasonic diagnosis device and makes it possible to conduct various high-quality or high-speed imaging. Reception signals obtained by an ultrasonic element group disposed in an array are digitized in a sampling cycle higher than a Nyquist frequency of the reception signals, and are mixed with reference signal. The mixed signals are then accumulated in a sampling direction, a number of the mixed signals accumulated being equal to a number of a plurality of samples, and are delayed and added by wave reception focusing means. The reference signal serially read out and used from memory means in such a manner as to correspond to the sampling number of the reception signals. A reference signal train acquired from signals, the frequency of which decreases gradually with a lapse of time, from wave transmission, or a reference signal train obtained alternately from two signals having different frequencies, may be stored in advance in memory means.

摘要： An ultrasound therapy apparatus delivers focused ultrasound for therapeutical purposes which can be correctly targeted to a target region, and also, a positional shift from the target region under irradiation of ultrasound can be effectively avoided. An ultrasound transducer is inside an applicator with an imaging ultrasonic probe. Another ultrasound transducer monitors a position of a target and a positional shift is inside a catheter which is inserted into a urethral tube. An imaging system drives the ultrasound probe to display an ultrasound tomographic image of a region in the vicinity of a target region. The ultrasound transducer is driven in a pulse-shaped mode at the same frequency as the imaging ultrasound and also at such timing when the imaging ultrasound is reached. As a result, a point-shaped sound source image is superimposed and displayed on an ultrasound tomographic image.
