From the Fig.12 and Fig.13 in the paper “A Helmholtz equation solver using unsupervised learning: Application to transcranial ultrasound” I find that most of the complex structure of the transverse CT slice in the field can be seen after just 200 iterations with this code. I am wondering can this code predict the sound field information at any given moment of a certain positionin in the brain? Or can I get a signal at this position that varies over time? Thanks a lot for your suggestions. |

If your goal is to do something like a wave simulation, i.e. a time-stepping simulation, then the answer is no. Although it is true that the wavefield resembles a wave simulation as the solution propagates, you can also see later on that the wavefield pattern is static. If your goal is to simulate the wave equation in the brain, I suggest you give a look at this paper and derived works. |

I believe is doing something similar to the WaveHoltz solver, although I'm not sure.
