Frequency dependence of attenuation and backscatter coefficient of ex vivo human lymphedema dermis

ConclusionFrequency independence of AC and BSC in LE ( −) and LE (+) was confirmed. Several 9- to 19-MHz ultrasound beams are sufficient for BSC analysis to discriminate LE (−) and LE (+) in terms of the penetration depth of the ultrasound.
