title = "Image reconstruction in photoacoustic tomography with truncated cylindrical measurement apertures",
abstract = "Photoacoustic tomography (PAT) is an inherently three-dimensional imaging technique with great potential for a wide range of biomedical imaging applications. In certain applications such as imaging of small animals or human limbs, it is natural to employ a measurement geometry in which the photoacoustic data are recorded on a cylindrical aperture. Analytic PAT reconstruction formulas are available for infinite cylindrical apertures, which are obviously not experimentally realizable. In this work, we investigate data sufficiency conditions and iterative reconstruction algorithms for exact image reconstruction in PAT assuming various truncated cylindrical measurement apertures. We employ known results regarding singularity detection in PAT to achieve this. Three-dimensional computer-simulation studies are conducted to corroborate the theoretical conjectures.",
