Incidence: Intensity Coefficients - Video Lesson

Hey, everyone. Welcome back to today's lesson on attenuation in ultrasound imaging. This lesson focuses on incidence, particularly incident intensity, reflected intensity, and transmitted intensity. As well as how these values combined with incidence angle predict ultrasound energy behavior. Understanding the behavior of ultrasound waves at tissue interfaces is fundamental to diagnostic medical sonography. Let's get started. Once an ultrasound wave leaves the transducer, it begins propagating through the body. Eventually, this sound wave will strike a boundary, whether that be between muscle and fat, soft tissue and bone, or any other two mediums. The pulse may reflect back towards the transducer or continue transmitting past the boundary. When discussing the energy of the sound wave when it strikes a boundary, we discuss the sound wave's intensity with three different terms.
