PRODUCTION METHOD FOR FLOW FIELD VISUALIZATION APPARATUS AND LIQUID CHANNEL MODEL, AND BLOOD FLOW SIMULATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide production methods for a flow field visualization apparatus and a liquid channel model and a blood flow simulation method facilitating an analysis of the blood flow of a living person.;SOLUTION: Two-dimensional tomographic data of the blood vessel of the person are collected using an apparatus for clinical diagnosis such as MRI. The shape of a three-dimensional model of the blood vessel is calculated using the two-dimensional tomographic data and a mold of the blood vessel inside is designed. Then, the mold of the blood vessel inside is produced using a powder lamination type RP (rapid prototyping) molding system. A blood vessel solid model is molded from the mold using a silicone rubber as a molding material. Glycerin aqueous solution containing a tracer and having the concentration from 30 wt.% to 56 wt.% is penetrated through the blood vessel solid model inside. The manner of the flow of the glycerin aqueous solution in the blood vessel solid model is analyzed by the moving quantity of the tracer.;COPYRIGHT: (C)2005,JPO&NCIPI
