Unfortunately there is no equivalent to <code>reorderSensorData</code> in 3D. One option would be to switch to using a Cartesian sensor mask. In this case the data will be returned in the same order as you specify the points.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/sphere-in-the-center-of-3d-transducer-geometry#post-6141 Wed, 27 Sep 2017 16:09:30 +0000 antonialongo1 6141@http://www.k-wave.org/forum/ <p>I figured out the problem.<br /> The reorder of the sensor data for 3D simulation is wrong.<br /> I noticed that there is the function 'reorderSensorData' for 2D simulation. Is there something equivalent for 3D? </p> <p>Thank you </p> http://www.k-wave.org/forum/topic/sphere-in-the-center-of-3d-transducer-geometry#post-6139 Tue, 26 Sep 2017 17:53:30 +0000 antonialongo1 6139@http://www.k-wave.org/forum/ <p>I am new with k_wave and I am using it to model photoacoustic signal.<br /> I am simulating a 3D transducer geometry (N transducers cylindrically focused, angular coverage of 270° and certain radius)<br /> As preliminary test, I am using a sphere as source p0.<br /> I have this problem:<br /> When I place the sphere at the center of the 3D transducer geometry, the sensor_data is consistent with my source (i.e. two rows corresponding to the optoacoustic signal of a sphere).<br /> When I place the sphere 3 mm far from the center of the 3D transducer, the row signal of some transducers seems to contain signal related to two spheres and not to one (as I am simulating).</p> <p>Thanks in advance! </p>
