Efficient regularization with wavelet sparsity constraints in photoacoustic tomography
In this paper, we consider the reconstruction problem of photoacoustic tomography (PAT) with a flat observation surface. We develop a direct reconstruction method that employs regularization with wavelet sparsity constraints. To that end, we derive a wavelet-vaguelette decomposition (WVD) for the PAT forward operator and a corresponding explicit reconstruction formula in the case of exact data....
متن کاملConvergence rates for regularization with sparsity constraints
Tikhonov regularization with p-powers of the weighted `p norms as penalties, with p ∈ (1, 2), have been lately employed in reconstruction of sparse solutions of ill-posed inverse problems. This paper points out convergence rates for such a regularization with respect to the norm of the weighted spaces, by assuming that the solutions satisfy certain smoothness (source) condition. The meaning of ...
متن کاملCompressed sensing and sparsity in photoacoustic tomography
Increasing the imaging speed is a central aim in photoacoustic tomography. This issue is especially important in the case of sequential scanning approaches as applied for most existing optical detection schemes. In this work we address this issue using techniques of compressed sensing. We demonstrate, that the number of measurements can significantly be reduced by allowing general linear measur...
متن کاملWavelet shrinkage using adaptive structured sparsity constraints
Structured sparsity approaches have recently received much attention in the statistics, machine learning, and signal processing communities. A common strategy is to exploit or assume prior information about structural dependencies inherent in the data; the solution is encouraged to behave as such by the inclusion of an appropriate regularization term which enforces structured sparsity constrain...
متن کاملComputationally efficient error estimate for evaluation of regularization in photoacoustic tomography.
The model-based image reconstruction techniques for photoacoustic (PA) tomography require an explicit regularization. An error estimate (?2) minimization-based approach was proposed and developed for the determination of a regularization parameter for PA imaging. The regularization was used within Lanczos bidiagonalization framework, which provides the advantage of dimensionality reduction for ...
