Verification of tensor measurements and validation of different fiber tracking algorithms with anisotropic diffusion requires a phantom with well known structure and anisotropic properties. In this work, the feasibility of using four different fiber phantoms for calibration measurements on a clinical scanner was investigated and their suitability for application of fiber tracking was tested. Among the tested fibers the dyneema fiber phantom was the most suited to validate diffusion tensor measurements. A fiber crossing phantom of dyneema fibers showed promissing results.
