Imaging of a benign tumor. (a) Ultrasound clinical B-mode image of a benign tumor. (b) Ultrasound Verasonics B-mode image of the same tumor. (c) 2D color map of the loss angle overlay on the B-mode image produced at 0.033āHz based on the LAM method. (d) 2D color map of the loss angle produced at 0.033āHz. (e) Normalized strain temporal behavior of the two specified points in (d) accompanied with a normalized stress profile. (f) Spectral behavior of the two specified points in (d) in a frequency range less than 1āHz.
