   Hi developer,
   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?
   Thanks in advance,
   qzshi

   Hi Brad

   Thank you for your reply. 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'.)

   Here is your code.
   % compute the FFT of the input data p(t, y) to yield p(w, ky) and scale
   p = sf .* fftshift(fftn(ifftshift(p)));

   qzshi.
