   hello,
   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?

   Hi elahehamini,

   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.

   Hi elahehamini,

   How to start to simulate PA image and reconstruct it? for example in the case of delay and sum?
   I am deeply grateful for any detailed information.

   Best,
   Mahdi

   Hi Mahdi,

   There are many examples of simulating and reconstructing photoacoustic images included in the toolbox. Open the MATLAB help browser, select k-Wave, and then Photoacoustic Image Reconstruction.
