In the B-mode imaging examples, the balls use noise with a higher standard deviation (i.e., more echoic) than the background. You could reverse this and see what happens.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/simulating-anechoic-hyperechoic-and-hypoechoic-cysts#post-7888 Mon, 26 Oct 2020 14:40:51 +0000 Farnaz 7888@http://www.k-wave.org/forum/ <p>Hello, </p> <p>I would like to simulate anechoic, hyperechoic and hypoechoic cysts. The b-mode image example looks like hyperechoic cysts to me. I couldn't find the setup to create for example anechoic cyst by reducing echogenicity but it doesn't work as I expect. What parameter should be changed? </p>
