Figure 2
Image-data mappings. An image (a) consisting of some explicit values, is organized according to the coordinate system \({\mathcal{I}}\). (b) Through the transformation effected by the forward model operator \(M\), one determines (c) the photoacoustic data in coordinate system \({\mathcal{D}}\). In practice, one acquires the data and (d) seeks to reconstruct the corresponding image through the action of some reconstruction operator \(R\). Iterative schemes are often favored for the reconstruction process, and so \(R\) is implicitly dependent on the operator \(M\). Figure created using a combination of MATLAB and Microsoft PowerPoint.
