摘要：
An image reconstruction formula is presented for photoacoustic computed tomography (PCT) that is valid for a layered medium in which some of the layers may be solids and detection is performed on a planar measurement surface. It is assumed that the optical absorber is embedded in a single fluid layer and any elastic solid layers present are separated by one or more fluid layers. Computer-simulation studies are used to validate the proposed reconstruction formula.
