Dear experts,
Thanks for the kwave toolbox which is very helpful for our study.
But we also encountered some problems. When using time reversal to reconstruct the photoacoustic image, we set the grid to 1000*1000 to get an image with better contrast, but the image is not detailed enough. When we set the grid to 2000*2000, the image details became more, but the image had more dot-like and streak artifacts, and the contrast of the image was severely reduced (the blood vessel color became very close to the background). What is the cause of this phenomenon?
Thank you,
Martin
