Good morning,
Here's some different uses for ultrasounds...
Ultrasound waves do not transmit well through dense bones or parts of the body that hold air or gas, however, such as the bowel. Medical procedures: Ultrasounds can be used to help guide certain procedures. Therapeutic applications: Ultrasounds can be used to detect and treat soft-tissue injuries.
Here's also what you can use a ultra sound for!
An ultrasound scan uses high-frequency sound waves to make an image of a person's internal body structures. Doctors commonly use ultrasound to study a developing fetus (unborn baby), a person's abdominal and pelvic organs, muscles and tendons, or their heart and blood vessels.
Hope this helps!! Have a good day!
