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： A method for examining a layer having defects and in particular the thickness of a machining damaged layer on a surface of a sample by means of a focused ultrasound beam and a device for realizing the method are disclosed, in which a focused ultrasound beam is generated and ultrasound reflected by the sample is detected. Curves (called V(z) curves) representing the relation of the distance between a transducer detecting the reflected ultrasound and the sample versus the detection output are traced while varying the distance and this measurement is repeated while varying the frequency of the focused ultrasound beam. The propagation velocity of surface acoustic wave in the sample is calculated on the basis of the period in each of the plurality of V(z) curves and a frequency dependence characteristic curve for the propagation velocity is obtained. The thickness of the machining damaged layer in the surface portion of the sample is evaluated from inflection points in the frequency dependence characteristic curve.

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.
