  • Patent number: 8304520
    Abstract: The present invention aims at providing a general-purpose experimental tool which specifically binds to a macromolecular substance that will be a receptor for a specific ligand such as drug, and is applicable throughout various processes to explore the nature of the macromolecular substance. In order to achieve this object, a molecular module has been developed which binds to a target compound and is used for purifying or labeling the target compound, wherein the molecular module has a rod-like spacer substance, an interacting substance that interacts with the target compound, a tag and a labeling substance, the interacting substance being positioned at one end of the rod-like spacer substance, and the tag and the labeling substance being positioned at the other end of the rod-like spacer substance.
    Type: Grant

  • Patent number: 7639865
    Abstract: It is an object of the present invention to acquire 3-dimensional image data that correctly express a structural configuration of the subject by processing the projected image data obtained by projecting the subject toward the plural angles . A shape computing unit 260 calculates shape data which represent a outline of the subject, using a plurality of 1st image data of the subject obtained by projecting the subject toward the plural angles. A distributing unit 220 generates gray-scale density-distributions by spreading and distributing densities shown in gray-scale image of the subject respectively within angles along which said gray-scale image was captured. A second integrating unit 240 generates 3-dimensional gray-scale data, which expresses the subject with the 3-dimensional image data, by integrating a plurality of said gray-scale density-distributions generated from a plurality of gray-scale image captured from a plurality of angles.

  • Patent number: 7379582
    Abstract: A projection image data captured from a plurality of angles is processed, and a three-dimensional image data accurately indicating a three dimensional structure for an object is obtained. A shape computing unit 260 computes shape data indicating an outline of a subject using a plurality of first image data of the subject captured from a plurality of angles. A distributing unit 220 generates a gray-scale density-distribution by extending and distributing density indicated in a gray-scale image of the subject acquired by a projection image capturing apparatus to an angle at which the gray-scale image is captured. The second integrating unit 240 generates a three-dimensional gray-scale data indicating the subject with three-dimensional image data by integrating a plurality of gray-scale images acquired from a plurality of angles and a plurality of gray-scale density-distribution. The first integrating unit 280 integrates the three-dimensional gray-scale image and shape data.

  • Patent number: 6828555
    Abstract: Verification of properness of a modeling theory of an uncrystallized substance or an image processing method is made easy. There includes: a first displaying unit 120 for rotationally displaying an simulated three-dimensionally shaded model image, which is a shaded image of the three-dimensional reconstruction image; and a second displaying unit 140 for displaying the three-dimensional image of the substance acquired by experimental structural analysis, which synchronously rotates with the simulated three-dimensionally shaded model image.
