Hi everyone,
I'm new to K Wave and I'm trying to simulate an ultrasound B mode image - I strongly follow the provided examples, except for adjusting the parameters to suit my needs.
I have an example experiment set up with:
phantom size 0.004m x 0.004m x 0.004m
dx = 0.22e-3m
automatic pml-generation
source strength 0.5e6
tone_burst_freq = 7e6
tone_burst_cycles = 5
number_scan_lines = 16
transducer_number_elements = 16
The B-Mode image ends up not resembling the grouund-truth image (voxel-cross-section) at all: Either it shows somewhat random signal, or it shows no signal at all (and the scan_lines consist mostly of NaN data). In the latter case, the simulation using C++ is much faster than usual. I checked the time step and it should be okay.
Any ideas where I should be looking for the issue?
