Viscoelastic parameters as discriminators of breast masses: Initial human study results - Fig 1

(a) SDUV technique is comprised of a push beam followed by a detection beam. The push beam perturbs the medium at the desired spatial location (illustrated in red) for 600μs. The detection beam is a spatially compounded beam (-2°, 0°, 2°) at a pulse repetition frequency (PRFd) of 3.3 kHz for 15 ms and is used to observe the propagating shear wave in the medium. (b) Flowchart summarizing the process of estimating tissue viscoelasticity from the data gathered in the detection phase.
