One option would be to stack your 2D image into a 3D image, adding some Gaussian noise to mimic diffusive scatterers. Alternatively, you could replicate the functionality of the 3D code in 2D, being mindful of the assumptions you are making in doing so (this will require a bit more coding).</p> <p>If you are just interested in producing something that looks a bit like an ultrasound image (and is computationally efficient), you could also take a look at ray-tracing methods, e.g., Shams, "Real-time simulation of medical ultrasound from CT images", 2008.</p> <p>Hope that helps!</p> <p>Brad </p> http://www.k-wave.org/forum/topic/example-to-generate-us-from-image#post-1269 Wed, 20 Feb 2013 14:14:21 +0000 pablitinho 1269@http://www.k-wave.org/forum/ <p>Hi,</p> <p>Is it possible to generate an US simulation from a single image?. I am new using this library and I dont understand it very well. As far as I have seen the example to generate the b-mode is in 3d, but I want in 2d. If it's possible to be done, please, can someone paste an example code?.</p> <p>Regards. </p>
