It has been suggested that fetal weight reduction by ultrasound exposure is linearly related to the dose parameter I2:t, where bdI is the intensity and bdt the exposure time. A direct test of the concept was conducted using CF-1 mice. No effect on fetal weight was found at values of the dose parameter large enough to produce measurable heating in the fetal and maternal tissues.
