Ultrasound imaging uses sound waves to produce images of the interior of the human body. Throughout the course of the pregnancy, the fetus may be inspected to identify the cause of the pregnant woman's pain, swelling, and infection. Baby hips, spine, and the brain are frequently examined with ultrasound. It can help with the assessment of heart attack damage, cardiac disorders, and biopsies. Ultrasound is a non-invasive, non-harmful procedure that uses no radiation at all.
