Anthropomorphic phantoms are an essential tool for the
validation of image registration algorithms of multimodal data and are important
for quantification experiments in 1H and 23Na MR imaging.
A human thorax phantom was developed with insertable lung, liver,
rib cage modules and tracking spheres. Evaluation regarding the tissue-mimicking characteristics with 1H and 23Na MR and CT imaging shows that
the modules possess T1, T2 and HU values comparable to those of human
tissues. This work presents an MR- and CT-compatible phantom which allows
experimental studies for quantitative evaluation of deformable, multimodal
image registration algorithms and realistic multi-nuclei MR imaging techniques.
