Essentially, you need to associate each time series with its corresponding measurement point.</p> <p>If, in addition, your measurement points are equally spaced and lying on a plane, you could look at the examples for <a href="http://www.k-wave.org/documentation/example_pr_2D_fft_line_sensor.php">2D here</a> or <a href="http://www.k-wave.org/documentation/example_pr_3D_fft_planar_sensor.php">3D here</a> for more inspiration.</p> <p>Ben </p> http://www.k-wave.org/forum/topic/how-to-reconstruct-an-image-from-data-taken-from-pat-measurement#post-3709 Thu, 13 Jun 2013 06:05:53 +0000 julehtel 3709@http://www.k-wave.org/forum/ <p>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?</p> <p>Thank you<br /> Juho </p>
