Correlation of Hemorrhage Near Developing Opossum Skull With Pulsed Ultrasound Exposure Parameters

High‐intensity focused ultrasound (HIFU) has been used noninvasively for therapeutic applications. Before HIFU can be used therapeutically on a human fetus, the bioeffects related to HIFU must be studied, and the mechanism causing the bioeffects should be understood. Previous studies have shown that HIFU, when targeted on fetal rat and mice bones. resulted in hemorrhage. However, the mechanism responsible has not been identified. In this study, we looked at ultrasound parameters related to hemorrhage in an effort to better understand the mechanism.
