Abstract
The subject disclosure presents systems and computer-implemented methods for determining an acoustic time-of-flight (TOF) of sound waves through a sample material with greater accuracy and in a more repeatable fashion, by invoking one or more of an envelope generation for an error function, fitting a non-linear curve to an ultrasound frequency sweep, or performing a clustered piece-wise linear regression on individual linear parts of the ultrasonic frequency sweep. The systems and methods are useful for, among other things, monitoring diffusion of fluids through porous materials, such as tissue samples.
