For optimization and validation of new dynamic
contrast-enhanced MRI sequences, a simple and cheap
perfusion phantom is developed. Contrast agent is
injected via a hose into a sponge and is washed out by a
constant water flow. The phantom can be quantitatively
described using a gamma-variate function, providing
heterogeneous parameter maps. The phantom experiment is
relatively well reproducible.
