How long can a transvaginal ultrasound wand be in a vagina before it causes cavitation or heating?

See answer. As a diagnostic procedure, ultrasound is a safe and painless procedure that uses sound waves to "see" inside your body and create detailed images. The wand, aka "transducer", used for diagnostic purposes does not emit heat or cause cavitation. When used as a therapeutic or treatment procedure, such as with liposuction, more powerful transducers are used which do emit heat and can cause cavitation.
Does not happen. Transvaginal ultrasound will not cause cavitation or heating. It utilize the sound wave not the radiation.
