An inverse problem formulation for parameter estimation of a reaction diffusion model of low grade gliomas
Amir Gholami, Andreas Mang, George Biros
We present a numerical scheme for solving a parameter estimation problem for a model of low-grade glioma growth. Our goal is to estimate the spatial distribution of tumor concentra…
