    摘要: Example embodiments of this invention include a method and a device for assessing the internal structure of the tooth. In one example, the method is comprised of emitting a sequence of ultrasonic pulses from a given point on the tooth surface into the tooth at various directions of incidence (angles of incidence) with respect to the local tooth surface, recording the corresponding sequence of ultrasonic echoes from different internal dental formations, and processing the collected ultrasonic pulse-echo and pulse-direction data to present internal structure of the tooth in quantitative or graphical form.

    摘要: A system and method for assessing the quality of spot weld joints between pieces of metal includes an ultrasound transducer probing a spot weld joint. The ultrasound transducer transmits ultrasonic radiation into the spot weld joint, receives corresponding echoes, and transforms the echoes into electrical signals. An image reconstructor connected to the ultrasound transducer transforms the electrical signals into numerical data representing an ultrasound image. A neural network connected to the image reconstructor analyzes the numerical data and an output system presents information representing the quality of the spot weld joint. The system is trained to assess the quality of spot weld joints by scanning a spot weld joint with an ultrasound transducer to produce the data set representing the joint; then physically deconstructing the joint to assess the joint quality.

    摘要: An ultrasonic device evaluates the sound velocity of a nail to determine the overall health of a patient and to monitor cosmetological effects of certain products on the nail. The ultrasonic device includes a handhold probe having an piezoelectric transducer encased in cover that emits high-frequency ultrasonic impulses directed towards the nail. The nail reflects returning ultrasonic echoes back to the piezoelectric transducer. The returning ultrasonic echoes vibrate the piezoelectric transducer. A processor of a computer converts the vibrations into electrical pulses. The processor evaluates amplitude values of the electrical pulses to determine the parameters of the human nail, including the thickness, density and elasticity. The parameters are displayed on a display and analyzed by a technician to determine the nail condition. The health of the person or the effect of products on the nail can be determined based on the nail parameters.

The platen is configured to receive the finger. The first transducer is arranged about the platen, configured to scan at least a portion of the finger by transmitting ultrasound waves toward the finger and receiving the ultrasound waves after the waves reflect off of the finger, and further configured to output signals based upon the received ultrasound waves. The drive system is configured to motivate the set of transducers arcuately about a central axis substantially parallel to the length of the finger to be scanned. The controller is configured to control the motion of the drive system. The software module is configured to receive a form of the signals from the first transducer and to compose the form of the signals into a three-dimensional representation of at least a portion of the surface tissue layer of the finger.
