  • Patent number: 5594849
    Abstract: A method and apparatus for performing biomagnetic imaging to determine the location and intensity of current sources within a subject includes a sensor unit for sensing the magnetic field within the subject and for providing sensing signals. A signal processor defines a grid having multiple grid points and performs inverse estimation to determine the distribution of current sources on the defined grid based on the sensing signals. The signal processor then modifies the grid to improve the resolution of the current sources distributed on the grid. A control unit controls the operation of the signal processor and processes image data to provide magnified and non-magnified displays on a display unit. The biomagnetic imaging method and apparatus can be combined with a system for providing magnetic resonance imaging data so as to produce a superimposed display including an MRI image and a biomagnetic image.

  • Patent number: 5115810
    Abstract: A plurality of rectangular piezo-electric ultrasonic sector transducers are aligned to form an array, and each transducer has first and second electrodes on its radiating surface. The first electrode is located on a center line of the sector transducer's length, and has a first length in the longitudinal direction and a first width along the center line. Two of the second electrodes are arranged outside the first electrode, symmetrical to the center line. The two second electrodes have a second length in the longitudinal direction longer than the first length, and have a second width which is almost the same as the first width, along a line near the center line. Thus, diamond-shaped electrodes excellent for providing a beam narrow in the longitudinal direction can be employed as the first electrode, and the combination of the first and second electrodes can be connected to each other.

  • Patent number: 4580451
    Abstract: An ultrasonic sector-scan probe comprises at least an array having a plurality of ultrasonic transducer segments, a window for transmitting and receiving ultrasonic waves and an ultrasonic wave propagation medium filled in a front space between the array and the window. A group of the ultrasonic transducer segments are selectively driven as an aperture and ultrasonic waves emitted therefrom are converged into a beam for transmission and reception. By partly or entirely changing the segments in the group with the ones outside the group the scan line is shifted to a new angle, and a member under test contacted with the window on the outside thereof is sector-scanned by the ultrasonic beam. The array is arranged so that scanning lines of the groups intersect at one point in the window or in its vicinity for sector scan.
