Ultrasound is a medical imaging technique that uses high-frequency sound waves to create images of organs and structures inside the body. It is commonly used in various fields, including obstetrics, where it helps monitor the development of a fetus during pregnancy. The procedure is non-invasive and does not involve radiation, making it a safe option for both patients and healthcare providers. In addition to obstetrics, ultrasound is also utilized in cardiology to assess heart conditions and in musculoskeletal imaging to evaluate injuries. The images produced can help doctors diagnose and treat a wide range of medical issues effectively.
