The simulation functions <code>kspaceFirstOrder1D</code>, <code>kspaceFirstOrder2D</code> and <code>kspaceFirstOrder3D</code> are used for time-reversal photoacoustic image reconstruction. </p> <p>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.</p> <p>Ben </p> http://www.k-wave.org/forum/topic/pat-back-projection-algorythm#post-1047 Thu, 22 Nov 2012 03:01:00 +0000 Pavel 1047@http://www.k-wave.org/forum/ <p>Dear Dr. Bradley Treeby and Ben Cox,</p> <p>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.</p> <p>Thank you and Regards,<br /> Pavel </p>
