title: Ultrasonically induced temperature elevation in mouse ovary.
abstract: Temperature increases, resulting from exposure to 1 MHz ultrasound, were measured in in situ and in exteriorized mouse ovaries. It is concluded that temperature increases from exposure to 10 W/cm2 and less are probably not significant for producing ovarian tissue damage, but that 25 W/cm2 exposures, and greater, are of such magnitude that damaging thermal levels ensue. The significance of blood flow in removing ultrasonically generated heat has been observed quantitatively.
