Frequency–depth images of FBH 2 for the phase difference: (a) LT, (b) LTC after six iterations, and (c) LTC after ten iterations; for the SNR-value: (d) LT, (e) LTC iteration six, and (f) LTC iteration ten; and for the diameter-size deviation: (g) LT, (h) LTC iteration six, and (i) LTC iteration ten. LT phase differences are displayed physically negated.
