Abstract

生体粘弾性係数同定問題に対する数値解法について考察する。この逆問題を制約条件付き最小化問題に変換して考える。我々は射影勾配法により,この最小化問題を解く方法を考えた。また数値実験により,本手法の有効性について検討する.

We will propose a numerical method for for identifying viscoelasticity of a living body from MRE measurement. We recast our inverse problem to a constrained minimization problem. The gradient projected method is applied to find the minimizing functions. We also confirm the effectiveness of our algorithm by numerical experiments.
