Diffusion weighted MRI is used to measure diffusion properties in the brain. In this paper, the method for the creation of an anatomically and mechanically realistic brain phantom from polyvinyl alcohol cryogel (PVA-C) and a 3D printable brain phantom using Poly Lactic Acid (PLA) PLA is proposed. PVA-C is material widely used in medical imaging phantoms because of its mechanical similarities to soft tissues. This brain phantom will allow testing and optimization of diffusion based MR methods.
