Mechanical ultrasound
WebIn Module 13 we look at familiar mechanical systems, often referred to as “ Typical and Non-Typical Rotating Equipment”. As ultrasound is NOT vibration, your instructor explains how ultrasound extends beyond rotating assets to assess systems with linear movements. WebJan 1, 2024 · Attenuation of ultrasound waves primarily occurs as the mechanical energy of the sound wave is converted into heat and absorbed by the tissues. Scattering of ultrasound waves is the next most prevalent cause of attenuation with other mechanisms including reflection, interference, divergence and diffraction making a small contribution.
