Abstract

The Role of Diagnostic and Therapeutic Ultrasound in Modern Medicine

Author(s): Amir Avan

Ultrasound has become a crucial tool in modern medicine, both for diagnostic and therapeutic purposes. Diagnostic ultrasound uses sound waves to create images of the internal structures of the body, while therapeutic ultrasound uses higher-frequency sound waves to produce heat and vibration that can be used to treat a variety of conditions. In this article, we will explore the science behind ultrasound technology, as well as its applications in modern medicine. Ultrasound is a form of energy that is transmitted as sound waves at a frequency that is above the range of human hearing (typically between 2 and 18 MHz). When these sound waves encounter tissues of different densities, some of the waves are absorbed, while others are reflected back to the transducer. The reflected waves are then converted into electrical signals and processed by a computer to create an image.
