Medical sonography, also known as ultrasound, is a diagnostic imaging technique that uses high-frequency sound waves to create images of the inside of the body. It is commonly used to visualize organs, tissues, and blood flow, helping healthcare professionals diagnose various medical conditions. The procedure is non-invasive and does not involve radiation, making it a safe option for patients. During a sonography exam, a trained technician, called a sonographer, applies a gel to the skin and uses a handheld device called a transducer to send and receive sound waves. The reflected sound waves are then converted into images displayed on a monitor, allowing doctors to assess the patient's health and make informed decisions about treatment.
