Hello,
I have developed a synthetic aperture simulation code by modifying the B-mode example. To define the time array I used the "set.Time" function as oppose to "Make.Time" while the former allows me to set the sampling frequency.
% create the time array
fs=20.83e6; % Hz
dt= 1/fs; % [s]
Nt=3000;
kgrid.setTime(Nt, dt)
I used the delay and sum image reconstruction method using the fs value to form an image. My simulated phantom is similar to the B-mode example. However my images are not clear and has major artifacts. The reconstruction algorithm was previously validated so the issue should be some sort of discrepancy between the simulation and reconstruction.
I was wondering if this was a correct approach to define the time array or if you have any other comments/suggestions.
Thank you in advance,
Dena
