I'm not sure how much success they had (I haven't seen the resultant images). In short, you need to add small-scale diffusive scatterers to your medium definition to generate the speckle pattern characteristic of ultrasound images. One approach would be to segment the MRI image in organs, define background properties based on book values, and then add noise to these values depending on the expected echogenicity of each tissue type.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/how-to-make-a-heterogeneous-scattering-us-phantom-for-b-mode-us-simulations#post-6765 Mon, 04 Mar 2019 10:13:55 +0000 sumit2868 6765@http://www.k-wave.org/forum/ <p>Hello,</p> <p>If I have an MRI or US image, and I want to make a heterogeneous phantom using this image, is there a way in K-wave to create an US phantom? </p> <p>I know in Field-II, there is a way to define the scattering amplitudes for different phantom locations to create such a phantom from a given MRI/US image. Can you please suggest something similar, if available, in the K-wave toolbox.</p> <p>Thanks,<br /> Sumit </p>
