Reconstruction formulas for photoacoustic sectional imaging

Abstract

The literature on reconstruction formulas for photoacoustic tomography is vast. The various reconstruction formulas differ in the measurement devices used and geometry on which the data are sampled. In standard photoacoustic imaging (PAI), the object under investigation is illuminated uniformly. Recently, sectional PAI techniques, using focusing techniques for initializing and measuring the pressure along a plane, appeared in the literature. This paper surveys existing and provides novel exact reconstruction formulas for sectional PAI. © 2012 IOP Publishing Ltd.
