In this work, we present a realistic phantom made of a solid material that we developed, which can mimic the human brain anatomy, including grey and white matter. Our new material also allows us to modulate T2 and susceptibility values by changing the ratios of a 4 component mix wich can result in T2 times from 100ms to 250ms and susceptibility values close to the human brain.
