Sonography, also known as ultrasound imaging, is a medical diagnostic technique that uses high-frequency sound waves to produce images of the internal structures of the human body. It is a non-invasive procedure that provides real-time visualization of organs, tissues, and blood flow without the need for radiation.

During a sonography examination, a specially trained technician, known as a sonographer, uses a handheld device called a transducer. The transducer emits sound waves into the body, and the echoes produced by the interaction of sound waves with internal structures are captured and converted into images by a computer.

Sonography has a wide range of applications in various medical specialties. It is commonly used in obstetrics to monitor the development of a fetus and detect any abnormalities. It is also valuable in assessing the health of organs such as the liver, kidneys, gallbladder, and heart. Additionally, it aids in the diagnosis of conditions like tumors, blood clots, and fluid collections.

The advantages of sonography include its non-invasive nature, real-time imaging capabilities, and the absence of ionizing radiation. It is a safe and widely available imaging modality that plays a crucial role in diagnosing and monitoring numerous medical conditions, contributing to improved patient care.
