High intensity focused ultrasound simulator

version 1.0 (180 KB) by

Simulates high intensity focused ultrasound beams and heating effects in layered media



View License

Contains two modules. The first solves the KZK equation for the pressure distribution of an axisymmetric focused ultrasound transducer, produces salient plots, and dumps the computed data to the Matlab workspace. The second module uses the pressure distribution to compute heating and thermal dose according to a user-defined treatment protocol. Again plots are produced and data is available for postprocessing.

Is anyone else having errors with the heating code example?


Really excellent code for HIFU simulation. It is very user-friendly and the outputs are very clean.

THe BHT_parameters.m program has some wrong.
t = [0:dt:T]; % time nodes
r = r(1:r_skip:round(J/2));
z = z(1:z_skip:M);
H = H(1:r_skip:round(J/2),1:z_skip:M);
[J,M] = size(H);
fprintf('\n\tdt = %2.2f sec\tN = %d\n',dt,N)
fprintf('\tdr = %2.2f mm\tJ = %d\n',10*r(2),J)
fprintf('\tdz = %2.2f mm\tM = %d\n\n',10*z(2),M)

Excellent code, but I didnt manage to change the parameters of sonication. I want to simulate a CW sequence of 60s and 48s of cooling. I set t_i=60 and t_c=48 and set number of pulses to 0 but the code persists on default values.


Excellent HIFU simulation codes!THANKS!

Well documented and with a large set of relevant output parameters.


Nice code, fast (axisymmetric calculation) and user-friendly.
It would be good to be able to specify more than 2 materials.


Should provide constants (alpha, beta, eta) for some other commonly used materials and media (like air) and/or cite sources on where to get them. Thanks


The software looks good although some basic sketches of the geometries, transducer positioning, materials, axes, naming conventions, etc. should be included in the instructions in order to understand basic examples and develop more advanced ones.
