Abstract:
Disclosed is a method for transmission and reception of ultrasonic beams using an array of ultrasonic transducer elements in which a plurality of transducer element sets each including the selected number of transducer elements for the transmission and/or reception of ultrasonic beams are sequentially selected. First and second sets having different focal axes defined relative to the plane of the transducer array are selected for the transmission and reception modes of operation respectively during the production of a single scan line. The position of at least one of the transducer elements in the first set is different from those of the transducer elements in the second set.

Abstract:
A deep-area temperature calculating device 441 calculates the temperature Tcore of a deep area on the basis of a first body-surface temperature and second body-surface temperature from body-surface sensors 31A and 31B, and on the basis of a first intermediate temperature and second intermediate temperature from intermediate sensors 32A and 32B. Since the temperature Tcore of the deep area is determined from two body-surface temperatures and two intermediate temperatures, the temperature Tcore of the deep area can be calculated regardless of the heat resistance of the thermometer without making any assumptions regarding the heat resistance of the area that extends from the deep area of the human body to the body surface. Thereby, the temperature Tcore of the deep area can be calculated and the body temperature can be measured with high precision regardless of differences in the body type or contact with clothing or bedding.
Abstract:
An object to the present invention is to provide an integrated-circuit package in which crosstalk can be reduced and impedance matching can be made. According to the present invention, conductive poles are grid-like arranged equidistantly in rows respectively in the vertical and transversal directions of an insulating substrate. The conductive poles are classified into signal conductive poles which are electrically connected to electrodes of the integrated circuit and the mother board, and earthed ground conductive poles arranged so as to adjacently surround the signal conductive poles.

Abstract:
An NMR imaging apparatus and method for direct Fourier imaging. This apparatus includes a static magnetic field generator, gradient magnetic field generators, high-frequency magnetic field generator, signal detecting detector for detecting a nuclear magnetic resonance signal from a body to be inspected, a computer for performing an arithmetic operation for the detected signal to obtain the nuclear magnetic resonance intensity distribution in the to-be-inspected body from measured values of the nuclear magnetic resonance intensity distribution at various points on a rectangular coordinate system in the Fourier space, and memories used for correction. In the imaging apparatus, that distortion of image data obtained by calculation from the detected signal which is caused by the deviation of the intensity of the static magnetic field from a predetermined value or the deviation of the intensity of a gradient magnetic field from a predetermined, linearly-varying intensity, is corrected by those measured values with respect to the above deviation of magnetic field intensity which are previously in the memory, and corrected image data is displayed on a display device.
Abstract:
An NMR imaging apparatus for reconstructing a cross section of a body to be inspected, by the projection-reconstruction method. That is, an apparatus for forming the above cross section in such a manner that the nuclear magnetic resonance is caused by the to-be-inspected body in the resulting magnetic field of a static magnetic field and a rotatable gradient field, a projection of the to-be-inspected body is detected at each rotational positions of the gradient field, and the cross section is reconstructed using the above projection. The apparatus comprises memories for previously storing therein data indicating the distorsion of magnetic field such as the non-uniformity of the static magnetic field and the non-linearity of the gradient field, in order to perform the coordinate calculation in the back projection, using the data stored in the memories.
