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. </p> <p>Best wishes<br /> Ben </p> http://www.k-wave.org/forum/topic/photoacoustic-reconstruction-using-delay-and-sum#post-9072 Sat, 30 Mar 2024 19:08:37 +0000 Jzzz 9072@http://www.k-wave.org/forum/ <p>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. </p> <p>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.</p> <p>Any help would be greatly appreciated! </p>
