Ultrasonography uses high-frequency sound waves and a transducer probe to produce images of the inside of the body. It is widely used due to its availability, speed, low cost, and the fact that it does not use radiation. Ultrasound can be used to evaluate symptoms, guide procedures like biopsies, and examine internal organs. It is commonly used in obstetrics to assess pregnancies and in gynecology to examine reproductive organs. The procedure involves applying gel and moving a transducer probe over the body to obtain images, which are displayed on a machine with components like a transducer, CPU, and display. Benefits include being non-invasive and providing real-time images, while limitations include
