In vivo ultrasonographic exposimetry: Human tissue–specific attenuation coefficients in the gynecologic examination
TA Siddiqi, M Miodovnik, RA Meyer… - American journal of …, 1999 - Elsevier
Objective: The purpose of the current study was to determine in vivo, tissue-specific
ultrasonic attenuation coefficients for each of the tissue layers comprising the anterior
abdominal wall, uterus, and vagina with use of a quantitative multilayer tissue model. We
wanted to validate the “homogeneous” tissue model-based Food and Drug Administration
derating factor of 0.3 dB/cm-MHz applied to obstetric-use ultrasonography systems. Study
Design: With use of a 3.0-MHz mechanical sector scanner and our previously tested …
