Open the MATLAB help browser, select k-Wave, and then <code>Photoacoustic Image Reconstruction</code>.</p> <p>Brad </p> http://www.k-wave.org/forum/topic/semicircular-sensor-with-sensor-angle-of-pi#post-7646 Thu, 25 Jun 2020 23:05:21 +0000 MahdiMajd 7646@http://www.k-wave.org/forum/ <p>Hi elahehamini,</p> <p>How to start to simulate PA image and reconstruct it? for example in the case of delay and sum?<br /> I am deeply grateful for any detailed information.</p> <p>Best,<br /> Mahdi </p> http://www.k-wave.org/forum/topic/semicircular-sensor-with-sensor-angle-of-pi#post-7018 Thu, 22 Aug 2019 17:55:27 +0000 Bradley Treeby 7018@http://www.k-wave.org/forum/ <p>Hi elahehamini,</p> <p>In this case, you will need to create the binary mask with the correct arc-angle, and the rotate/flip the matrix so that it is aligned the same way as the Cartesian mask.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/semicircular-sensor-with-sensor-angle-of-pi#post-6950 Fri, 05 Jul 2019 13:50:19 +0000 elahehamini 6950@http://www.k-wave.org/forum/ <p>hello,<br /> when I try to run the 2D Time Reversal Reconstruction For A Circular Sensor Example for a sensor angle of -pi, the Cartesian sensor mask works fine but when it's creating a binary sensor mask of an equivalent continuous circle, it just gives a single point sensor and therefore the wrong reconstruction. what should I do for a -pi angle? </p>
