need help on using Delay and Sum algorithm to reconstruct an image

Hi everyone.

I have a problem on reconstructing an image from scattered signals using DAS algorithm. I have the follwong code so far. I have 10 arrays located on a box same location that I put in the code. Actually i used the code from DAS beamfoemer from this website and then I tried to modify it based on my requiremnets.

I need to know how can I load my own signal? I tried to load it, but it didnt work.

and I need to get the image on my box but it shows on the sphere.

Could any one help me? really appreciate it.
