  • Phantom for diffusion tensor imaging
    Patent number: 7667458
    Abstract: 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.
    Type: Grant
