   Hello, I am new to k-wave toolbox and photoacoustic imaging. I am trying to simulate photoacoustic data with very simple set up: a linear array sensor and a circular source. After running kspaceFirstOrder2D, I got a sensor element vs. dt data matrix.

   I am confused to what are the next steps to perform delay and sum? I understand that DAS requires multiple scan lines data, but I don't know how exactly do I simulate that in kwave toolbox.

   Any help would be greatly appreciated!

   Hi Jzzz,

   It sounds as though you have simulated the data you need in order to be able to do a photoacoustic reconstruction. There are various ways to do reconstructions. Delay-and-sum is not implemented in k-Wave but there are other methods you could use. Look at the examples that come with the toolbox, under the 'Photoacoustic Image Reconstruction' heading.

   Best wishes
