In this work we present a solid brain phantom that resemble the anatomy and T2 relaxation times of the brain. The developed material is a 3-component mix. Adjusting the relative concentration of the compounds allow to modulate T2 relaxation time, following a linear relationship within a range of 145 to 263ms. The resulting solid phantom can reproduce correctly the geometry of white and gray matter. The range of achievable T2 relaxation times makes possible the construction of phantoms that could mimic a wide range of biological tissues.
