Abstract :
Estimating the permittivity value for the internal breast structure can be useful towards enhancing a Delay-and-Sum (DAS) algorithm. This paper introduces a frequency-domain MUSIC super-resolution algorithm for estimating the time-of-flight (ToF) of signals travelling through the breast tissues considering Bristol´s 31-element experimental system.
