Hello All,
Long time k-Wave user here. In the past, I've mostly used the 2D simulator, but I recently started using the 3D codes to simulate data for 3D ultrasound tomography.
I noticed that when I ran the same simulation in kspaceFirstOrder3D vs kspaceFirstOrder3DG, I would get different results. The difference between the results is not simply roundoff error. There are significant delays between the signals simulated by kspaceFirstOrder3D vs kspaceFirstOrder3DG. I suspect the discrepancy might have to do with dispersion. Are there any known (or unknown?) dispersion-related issues with kspaceFirstOrder3DG?
Please let me know if you would like me to share some sample code with the example that produces the discrepancy.
Thank you,
Rehman Ali
