But I have another question. Why do you use function 'ifftshift' before 'fft' in the function 'kspaceLineRecon' line 179?(I think function 'ifftshift' should be use after 'ifft'.)</p> <p> Here is your code.<br /> % compute the FFT of the input data p(t, y) to yield p(w, ky) and scale<br /> p = sf .* fftshift(fftn(ifftshift(p)));</p> <p>qzshi. </p> http://www.k-wave.org/forum/topic/2d-fft-reconstruction-for-a-line-sensor-example#post-7359 Fri, 03 Apr 2020 15:10:33 +0000 Bradley Treeby 7359@http://www.k-wave.org/forum/ <p>Hi qzshi</p> <p>Have a look <a href="http://bug.medphys.ucl.ac.uk/papers/2010-Treeby-JBO.pdf">here</a>.</p> <p>Brad </p> http://www.k-wave.org/forum/topic/2d-fft-reconstruction-for-a-line-sensor-example#post-7356 Fri, 03 Apr 2020 03:25:43 +0000 qzshi 7356@http://www.k-wave.org/forum/ <p>Hi developer,<br /> Where can I get more details of '2D FFT Reconstruction For A Line Sensor' example. I can not fully understand how the function kspaceLineRecon works. In other words, I would like to know the model of algorithm in this function. Can you give me some references of this example?<br /> Thanks in advance,<br /> qzshi </p>
