A correction coefficient (52) with respect to the displacement of each beam line is calculated on the basis of the calculated displacement gradient (e), and the displacement distribution measured on the basis of the calculated correction coefficient is corrected (f).

    Abstract: A non-contact measuring method in pediatrics is disclosed. An infant model is established by acquiring a human image and a depth image of a subject infant; updating the infant model by acquiring a plurality of anthropometric characteristic points and finally obtaining an anthropometric data of the subject infant from the updated infant model. This invention also provides an apparatus to achieve the above mentioned measuring method. An infant model which includes anthropometric characteristic points and 3D surface models is established based on a human image acquired by an image acquisition module and a depth image acquired by a depth information acquisition module in conjunction with an algorithm program built in a data acquisition and processing module. Human anthropometric data is obtained by analyzing the infant model. The non-contact measuring method and measuring apparatus in pediatrics make the measuring process more humane without contacting a subject body.

  • Patent number: 8647276
    Abstract: In a radiation-pressure elastography technique for transmitting a ultrasound focused beam into a test object body and diagnosing the hardness thereof, it is required to consider high sensitivity and safety. In the present invention, the focused beam is transmitted to two positions as a means for displacing a tissue and exciting a shear wave. In addition, time control is performed in such a manner that a transmit beam serves as a burst-chirp signal, and ultrasound waves are transmitted and received while sweeping a transmit frequency. On this occasion, when the distance between the two focused points and the transmit frequency become integral multiple of the wavelength, two waves interfere with each other, thereby obtaining a large amplitude. Furthermore, when the transmit frequency becomes equal to a resonance frequency peculiar to the tissue, the amplitude also becomes larger. Accordingly, a small intensity of transmit waveform enhances sensitivity.

    Abstract: In an ultrasonic measuring apparatus, an addition/averaging-period setting unit determines a blood vessel diameter stable period in which a blood vessel diameter is in a stable state in one heartbeat period and sets the blood vessel diameter stable period as an addition and averaging period. An adding and averaging unit adds up and averages reflected wave measurement data measured in the addition and averaging period set by the addition/averaging-period setting unit. A blood-vessel-diameter calculating unit calculates a blood vessel inner diameter of a blood vessel using combined data obtained by the addition and averaging of the adding and averaging unit.
