R2A. Multiview TomographyR2A. Multiview Tomography
Focus of research: Image formation from tomographic measurements Modalities of interest in CenSSIS:
EIT, ERT, DOT, GPR, diffraction tomography, CT, ultrasound, elastography
Diverse applications approached through a common view: statistical physics-based inverse scattering Inverse problem goals + physics model +
solution representation + robust decision-directed algorithm
Objective: Improved resolution, signal-noise in subsurface imaging
