Medical 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 providers assess various medical conditions. The procedure is non-invasive and does not involve radiation, making it a safe option for patients. During a ultrasound exam, a small device called a transducer is placed on the skin, emitting sound waves that bounce off internal structures. The returning echoes are then converted into images displayed on a monitor, allowing doctors to evaluate the patient's health and make informed decisions about treatment.
