Reconstruction Formulas for Photoacoustic Sectional Imaging
The literature on reconstruction formulas for photoacoustic tomography (PAT) is vast. The various reconstruction formulas differ by used measurement devices and geometry on which the data are sampled. In standard photoacoustic imaging (PAI), the object under investigation is illuminated uniformly. Recently, sectional photoacoustic imaging techniques, using focusing techniques for initializing a...
متن کاملPhotoacoustic Sectional Imaging and Reconstruction Formulas for a Single Scattering Model
We consider photoacoustic sectional imaging experiments. Opposed to standard photoacoustic imaging (see e.g. [9, 8, 6, 10] for some mathematical and physical review papers), where the detectors record sets of two-dimensional projection data over time, from which the three-dimensional imaging data can be reconstructed, in sectional imaging, a single scan procedure is implemented to be able to re...
متن کاملGradient-Based Quantitative Photoacoustic Image Reconstruction for Molecular Imaging
The aim in quantitative photoacoustic imaging (QPI) is to recover the spatial distributions of the optical absorption and scattering coefficients from an absorbed energy density distribution (a conventional photoacoustic image). This paper proposes a gradient-based minimisation approach and demonstrates that functional gradients may be calculated efficiently by using a finite element model of l...
متن کاملModelling the Effect of Focusing Detectors in Photoacoustic Sectional Imaging
To effectively use photoacoustic tomography to obtain cross-sectional images, a combination of a focused laser illumination and focusing acoustic detectors is used. In this work, we discuss how to incorporate cylindrically shaped focusing detectors in the mathematical modelling of photoacoustics and derive approximative reconstruction formulas. Moreover, we show how such focusing detectors comb...
متن کاملNanoparticles for photoacoustic imaging.
Nanoparticles have been designed and applied as contrast enhancers in various optical imaging techniques, such as optical coherence tomography, fluorescence imaging, and optical reflectance microscopy. As an emerging hybrid imaging modality, photoacoustic imaging (PAI) has also benefited from the application of these nanoparticle-based contrast agents. We review this rapidly growing field and d...
