PHANTOM FOR DIFFUSION TENSOR IMAGING

摘要

A phantom for diffusion tensor imaging is provided to measure main physical quantities of diffusion tensors, such as diffusion anisotropy, a diffusion principal axis and a route of the diffusion principal axis. An outer container(11) provides an accommodation space. Materials(12 - 16) for diffusion measurement are located in the space of the outer container, and are composed of bunches of micro tubes. Fixing materials(17) are located in the space of the outer container to fix the materials for diffusion measurement to a specific location. The outer container is formed of acrylic resin.
