   Dear Dr. Bradley Treeby and Ben Cox,

   First of all, thank you very much for nice toolbox that allows to feel photoacoustics fast end easy. I am just curious if there are any Back-Projection Algorythm examples.

   Thank you and Regards,
   Pavel

   Hi Pavel,

   The only photoacoustic image reconstruction algorithms we currently include are kspacePlaneRecon which reconstructs data measured over a planar measurement surface (there is a 2D version kspaceLineRecon), and time reversal, which can be used for any geometry of measurement surface. The simulation functions kspaceFirstOrder1D, kspaceFirstOrder2D and kspaceFirstOrder3D are used for time-reversal photoacoustic image reconstruction.

   These are included as they are the ones actually used by the Photoacoustic Imaging Group at UCL. Neither of these are implementations of explicit backprojection formulas. There are many exact backprojection formulas to choose from for photoacoustic imaging, and all of them (if implemented as backprojections) are computationally slow.
