摘要
Medical ultrasound (US) imaging, also known as echography, is one of the most frequently used frontline clinical imaging modalities and is characterized by its safety, affordability, accessibility, and real-time image display. Sound pulses, typically in the megahertz range, are sent into the body and the backscattered echoes are used to create a tomographic image. The contrast of an US image arises from local variations in the physical properties of the tissues, primarily density and elasticity, revealing tissue structures at depth.
