Tomographic studies typically employ a single forward/inverse modelling formalism to derive models of subsurface properties. Various formalisms may involve different approximations and parameterizations leading to different biases. Moreover, many studies are motivated by “low-dimensional” questions that are addressed through human-biased interpretation of the “high-dimensional” and intrinsically biased model.
Zhao et al.  demonstrate how multiple tomographic formalisms can be used simultaneously to remedy these deficiencies. They do so through an elegant probabilistic interrogation-theoretic framework applied to toy and real-world examples that validate their approach and serve as tutorials for tomographic practitioners.
