Probability-based Diagnostic Imaging

Based on Delay and Sum DAS Algorithm

The program generates Probability-based Diagnostic Imaging established by an actuator-sensor path in terms of ToF extracted from Lamb wave signals.

[I_final] = DMAS(x,t,Acx,Acy,Snx,Sny,Cg,meshsize)
%x = Received Signals N x M matrix
% t = corresponding Time N x 1 vector
% Acx,Acy = Actuators position in mm n x 1 vector/scalar
% Snx,Sny = Sensors position in mm n x 1 vector/scalar
% Cg = Wave velocity in m/s
% Meshsize = Number of pixels
% For Example
% load example.mat
% [I] = DMAS(x,t,[100 100],[500 500],[250,250],[500 300],5920,700);
