   Hi Dr. Cox and Dr. Treeby, I am a electrical engineering student from Finland. I have been trying to reconstruct an 2D image from data I have measured with PAT. The problem is that my data is in a 'matrix' and it contains only amplitude values. So that one measurement data goes on one row and the second measurement on the second when I move the sample. I have been using example_pr_2D_FFT_line_sensor as the base. So my question is that what do I need to do to get an image out of my data?

   Thank you
   Juho

   Hi Juho,

   If each row of your matrix contains a photoacoustic pressure time series recorded at one point, then you could try reconstructing the image using time reversal (see the examples such as this for the details of how to set it up). Essentially, you need to associate each time series with its corresponding measurement point.

   If, in addition, your measurement points are equally spaced and lying on a plane, you could look at the examples for 2D here or 3D here for more inspiration.
