Hello,
I hope you can help me.
I'm new to K-wave (and MATLAB until relatively recently).
As part of a university project I am attempting to create a simulated B-mode image of a tissue mass with a spherical tumour within it.
To distinguish the tumour from the bulk tissue, I plan to use Effective Scatterer Diameter (ESD) as a distinguishing parameter, and see over a range of values what difference in ESD is required between the bulk tissue and tumour in order to identify the tumour on a B-mode image.
I am attempting to modify the "Simulating B-mode Ultrasound Images Example" for my purposes.
I wish to replace the three spheres with one spherical (or cubic) region which contains a number of smaller spheres (representing my effective scatterers). The diameter of these smaller spheres will vary over a small range, as will their speed of sound values (just like the three spheres in the example currently do).
Can you suggest how I might create this mass of spheres?
Any help at all would be much appreciated!
Thank you,
David
