Title: Yutaka Ohtake: Innovator in X-ray CT Technology
Introduction
Yutaka Ohtake is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of dimension measurement and X-ray computed tomography (CT). With a total of 8 patents, Ohtake's work has advanced the precision and efficiency of measurement techniques in various applications.
Latest Patents
One of Ohtake's latest patents is a dimension measurement method using projection images obtained by an X-ray CT apparatus. This innovative method involves obtaining multiple transmission images of an object made of a single material. The projection images are then registered with CAD data used in designing the object. By utilizing the relationship between the registered CAD data and projection images, high-precision dimension measurement is achieved without the need for CT reconstruction.
Another notable patent is a surface extraction method and apparatus for X-ray CT volume. In this invention, an isosurface mesh is generated by extracting voxels with specific CT values from volume data. A gradient vector of the CT value is calculated at each vertex of the isosurface mesh. Sample points are generated in both positive and negative directions of the gradient vector, and the vertex is corrected to a sample point with the maximum norm calculated. This method enhances the accuracy of surface extraction in X-ray CT applications.
