  • Publication number: 20170270706
    Abstract: A three-dimensional region of interest (ROI) is established with a high degree of accuracy, by a simple method without increasing a burden on the operator, in generating a three-dimensional projected image from medical volume data according to rendering, achieving more efficient interpretation of three-dimensional image and streamlining of diagnostic flow, with the use of the diagnostic image generation apparatus. An energy map is generated on a predetermined tomographic plane, assuming a preset start point as a reference and searching for a path that minimizes the energy, and then the path is set as a boundary of the three-dimensional ROI. The start point may be decided on the basis of the boundary inputted by a user, or the user may set the start point. The user may be allowed to adjust the boundary having been set. The boundary may also be determined on another plane orthogonal to the predetermined tomographic plane.

    Abstract: In a semiconductor device, a first conductivity-type first semiconductor region that abuts on a side surface of a contact trench adjacent to an opening portion of the contact trench, and has a higher impurity concentration than that of a second semiconductor layer is formed. Also, a second conductivity-type second semiconductor region that abuts on a bottom surface of the contact trench and a side surface of the contact trench adjacent to the bottom surface of the contact trench, and has a higher impurity concentration than that of a first semiconductor layer is formed. A first electrode that is connected electrically with the first semiconductor region and the second semiconductor region is disposed in the contact trench. Even when the semiconductor device is miniaturized by reducing the width of the contact trench, a breakage of the semiconductor device when switched from an on-state to an off-state is reduced.
