    摘要: A method and system for acquiring a phalange edge image using an X-ray image of a hand are provided. The method includes: selecting a region of interest from an X-ray image of the hand; acquiring a soft tissue background gray level removed image by removing a soft tissue background gray level from the region of interest; and extracting a phalange edge image from the soft tissue background gray level removed image.

    摘要: A phantom for Diffusion Tensor Imaging (DTI) to measure the main physical quantities of diffusion tensors, such as diffusion anisotrophy, a diffusion principal axis and a route of the diffusion principal axis, and to evaluate the accuracy of DTI are provided. The phantom for diffusion tensor imaging includes: an outer container providing a space; materials for diffusion measurement located in the space of the outer container and formed of bunches of microtubes; and materials for fixing located in the space of the outer container to fix the materials for diffusion measurement to a specific location.
