Current 3D photoacoustic tomography (PAT) systems offer either high image quality or high frame rates but are not able to deliver high spatial and temporal resolution simultaneously, which limits their ability to image dynamic processes in living tissue (4D PAT. [] Key Method We demonstrate that combining model-based, variational image reconstruction methods using spatial sparsity constraints with the development of novel PAT acquisition systems capable of sub-sampling the acoustic wave field can…

This work shows how a further increase of image quality or acquisition speed rate can be achieved for imaging dynamic processes in living tissue (4D PAT) by coupling the previously used spatial image reconstruction models with sparsity-constrained motion estimation models.

A framework for directional and higher-order reconstruction in photoacoustic tomography

Enhancing sparse-view photoacoustic tomography with combined virtually parallel projecting and spatially adaptive filtering

An iterative sparse-view PAT reconstruction scheme is presented, where a concept of virtual parallel-projection matching the measurement condition is introduced to aid the “compressive sensing” in the reconstruction procedure, and meanwhile, the non-local spatially adaptive filtering exploring the a priori information of the mutual similarities in natural images is adopted to recover the unknowns in the transformed sparse domain.

An iterative sparse-view PAT reconstruction scheme where a virtual parallel-projection concept matching for the proposed measurement condition is introduced to help to achieve the “compressive sensing” procedure of the reconstruction, and meanwhile the spatially adaptive filtering fully considering the a priori information of the mutually similar blocks existing in natural images is introduction to effectively recover the partial unknown coefficients in the transformed domain.
