You can access these via the MATLAB help browser (see Section 1.3 in the k-Wave manual if you can't find it). They are also accessible via the /examples folder.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/simulating-b-mode-images-using-a-single-element-transducer#post-5354 Tue, 12 Jan 2016 15:05:48 +0000 marlenep 5354@http://www.k-wave.org/forum/ <p>Hi Ben! </p> <p>it would be possible to have the complete code of the "Simulating B-mode Ultrasound Images Example" ?</p> <p>I'm trying to do the same just to understand how the toolbox works but my results don't convince me and i don't know if I make some errors in the post processing or in the previous steps.</p> <p>thank you very much for any suggestion </p> <p>Marlene </p> http://www.k-wave.org/forum/topic/simulating-b-mode-images-using-a-single-element-transducer#post-5042 Sun, 12 Apr 2015 18:06:24 +0000 bencox 5042@http://www.k-wave.org/forum/ <p>Hi Elyas,</p> <p>Yes, you can define the source and sensor to be the same pixels. Just make sure your source toneburst is short enough that the sensor is not just detecting the source values you're inputting, but is detecting the signal backscattered from the medium.</p> <p>Ben </p> http://www.k-wave.org/forum/topic/simulating-b-mode-images-using-a-single-element-transducer#post-5040 Fri, 10 Apr 2015 22:27:25 +0000 elyas 5040@http://www.k-wave.org/forum/ <p>Thanks Ben. In the example that you mentioned, the transducer acts as a detector and two point sources act as the source of spherical waves.<br /> Is it possible to define a single-element focused transducer (for example, using the makeSphericalSection function) to be the source and the sensor, while the scanning a medium similar to the medium defined in the example "Simulating b-mode ultrasound images"? </p> <p>Thanks,<br /> Elyas </p> http://www.k-wave.org/forum/topic/simulating-b-mode-images-using-a-single-element-transducer#post-5038 Wed, 08 Apr 2015 16:29:10 +0000 bencox 5038@http://www.k-wave.org/forum/ <p>Dear Elyas,</p> <p>To simulate a single focussed transducer see the <code>Focussed Detector in 3D Example</code>. Then, one way to form a B-mode image would be to set up a for-loop and run one simulation per loop, moving your single focussed transducer along a bit each time.</p> <p>Hope that helps,<br /> Ben </p> http://www.k-wave.org/forum/topic/simulating-b-mode-images-using-a-single-element-transducer#post-5032 Tue, 07 Apr 2015 20:40:08 +0000 elyas 5032@http://www.k-wave.org/forum/ <p>Hi Brad,</p> <p>I want to modify the example “Simulating b-mode ultrasound images” to generate RF data by lateral translation of a single-element focused transducer. Can you please provide an example or suggestions on how to proceed?</p> <p>Thanks,<br /> Elyas </p>
