title: Absorption of ultrasound by mammalian ovaries.
abstract: The transient thermoelectric method was employed to determine the ultrasonic absorption coefficient of excised bovine, canine, feline, murine, ovine, and porcine ovaries at 1 MHz. The dynamics of the organ yields significant variations with physiological stage and structure. Values ranged from 0.017 cm-1 for the follicle to 0.050 cm-1 for the corpus luteum, largely reflecting macromolecular content. Little interspecies variation was observed.
