Application of the Finite Element Method in a Quantitative Imaging technique
For medical imaging researchers, this provides a numerical approach to reconstruct coefficients from single-measurement data, but the results are preliminary with no comparison to existing methods.
The paper applies the Finite Element Method (FEM) to solve a multidimensional coefficient inverse problem for quantitative imaging, achieving quantitative reconstruction of sound speed in small tumor-like inclusions.
We present the Finite Element Method (FEM) for the numerical solution of the multidimensional coefficient inverse problem (MCIP) in two dimensions. This method is used for explicit reconstruction of the coefficient in the hyperbolic equation using data resulted from a single measurement. To solve our MCIP we use approximate globally convergent method and then apply FEM for the resulted equation. Our numerical examples show quantitative reconstruction of the sound speed in small tumor-like inclusions.
