文摘
- •
We explore the potential of low-frequency tomography for breast cancer diagnosis.
- •
Using full data, reflection and transmission, allows sub-wavelength reconstruction.
- •
The problem is treated as a coefficient inverse problem for the wave equation.
- •
The algorithms are based on direct computation of the gradient of the residual.
- •
Parallel algorithms focus on the use of GPU clusters and supercomputers.
