The paper proposes a reconstructive source imaging procedure for diffusive ultrasound modulated bioluminescence tomography (UMBLT) in optically anisotropic media with partial data and uncertain optical parameters.
Samenvatting
The paper studies an imaging problem in diffusive ultrasound-modulated bioluminescence tomography (UMBLT) with partial boundary measurement in an anisotropic medium. Assuming plane-wave modulation, the authors transform the imaging problem to an inverse problem with internal data and derive a reconstruction procedure to recover the bioluminescent source. Subsequently, an uncertainty quantification estimate is established to assess the robustness of the reconstruction.
The key highlights and insights are:
Reconstruction in Optically Anisotropic Media: The authors generalize the reconstruction procedure for diffusive UMBLT to optically anisotropic media, providing a more comprehensive understanding of UMBLT imaging in complex media.
Reconstruction with Partial Data: The authors extend the reconstruction procedure to the case where data is only available on a partial boundary, furnishing a theoretical underpinning for source imaging with limited data acquisition.
Uncertainty Quantification: The authors derive a quantitative uncertainty estimate using the PDE theory of second-order elliptic equations, demonstrating how the variance of the source is linked to the variance of the optical parameters.
Discrete Formulation: The authors discretize the diffusion equation using the staggered grid scheme to yield a discrete formulation of the UMBLT inverse problem, facilitating numerical implementation and validation.
