of diameter. Therefore, the vessel model for simulating intervention
is now required to reproduce that thin-vessel lumen too. However,
other available fabrication methods do not satisfy that requirement.

Hence, it is very helpful to materialize the fabrication method
that allows constructing patient-tailored vessel model with sub-
millimeter modeling resolution. And in this patient-tailored
modeling, it is desirable to use medical imaging information such as
CT, MR and ultrasonic diagnosis, which are commonly available for
every case. This kind of patient-tailored high-precision vessel model
should provide a helpful medical platform for diagnoses, preliminary
simulations, pathological (hemodynamic) studies, surgical training,
and testing of medical instruments.
