  • Patent number: 9220477
    Abstract: An ultrasonic diagnostic apparatus includes a controller, to which a probe and a monitor are connected, the probe having an array of transducers, in which a number of transducers are arranged in a first direction. The controller controls transmission of an ultrasonic beam using the array of transducers and reception of an echo signal reflected from a region of interest, generates image data based on the echo signal, and gets echo signals received from multiple points of the region of interest by either moving or swinging the array of transducers in a second direction that intersects with the first direction at right angles. If the sum of image data ranges of measured value retrievable portions of the region of interest at the multiple points synthesized based on the echo signals, is equal to or greater than a predetermined value, the controller calculates a detected value of the region of interest.

  • Patent number: 8886283
    Abstract: Magnetic susceptibility is the physical property for T2*-weighted magnetic resonance imaging (T2*MRI). The invention relates to methods for reconstructing an internal distribution (3D map) of magnetic susceptibility values, ? (x,y,z), of an object, from 3D T2*MRI phase images, by using Computed Inverse Magnetic Resonance Imaging (CIMRI) tomography. The CIMRI technique solves the inverse problem of the 3D convolution by executing a 3D Total Variation (TV) regularized iterative convolution scheme, using a split Bregman iteration algorithm. The reconstruction of ? (x,y,z) can be designed for low-pass, band-pass, and high-pass features by using a convolution kernel that is modified from the standard dipole kernel. Multiple reconstructions can be implemented in parallel, and averaging the reconstructions can suppress noise.
