  • Patent number: 8953739
    Abstract: An image processing apparatus and X-ray CT system, having a tracheal bifurcation area extraction part, for extracting the tracheal bifurcation area from an X-ray image and a tracheal bifurcation identification part, for identifying the tracheal bifurcation from the tracheal bifurcation area.
    Type: Grant
    Filed: May 13, 2011
    Date of Patent: February 10, 2015

    Inventors: Tatsuo Maeda, Manabu Hiraoka, Naoko Toyoshima
  • Patent number: 8731252
    Abstract: A storage unit stores data of a first image associated with a contrast-enhanced cardiac region. A specification unit specifies a specific region included in the cardiac region on the basis of a distribution of pixel values of the data of the first image. A setting unit contracts the specified specific region, and set an ROI to the contracted specific region. A calculation unit calculates an index concerning the set ROI. The index is associated with a function of the specific region.

  • Patent number: 8320658
    Abstract: An unevenness inspection method for inspecting presence of unevenness in a panel material, the method includes: acquiring a plurality of primary images by imaging the panel material under inspection on a plurality of levels of condition; creating a plurality of secondary images by processing the plurality of primary images to enhance variation of the image; creating a composite image by combining the plurality of secondary images with a prescribed weighting; and determining the presence of unevenness using the composite image, the prescribed weighting being determined so that a region having the unevenness can be distinguished from the other region, when the plurality of secondary images are created for the panel material for training use having unevenness and are combined into a composite image.

  • Publication number: 20080030524
    Abstract: An imaged picture is obtained by imaging the display panel having a plurality of periodically arranged image elements by an imaging device having a plurality of periodically arranged imaging components, by imaging each image element of the display panel by a plurality of the imaging components. Then a reduced picture is created by specifying position and area of each region including a plurality of pixels consecutively arranged in the imaged picture randomly in a prescribed range and combining the plurality of pixels in the region into one pixel.

  • Publication number: 20070098134
    Abstract: An X-ray computed tomography apparatus calculates transfer functions h(t) using a time-concentration curve Ca(t) for pixels of a cerebral artery and a time-concentration curve Ci(t) for pixels of cerebral tissues including capillary vessels and then calculates a delay time for each pixel of an object region from a time when an artery curve rises on the basis of the transfer functions. Further, the apparatus differently produces a visual color map showing time differences of blood flow conditions and provide it in a predetermined form by coloring pixels with a time delay from the other pixels without a time delay on the basis of the calculated delay time.
