Ultrasoundbased
Ultrasound-based refers to techniques and devices that use ultrasonic waves, typically in the megahertz range, to transmit, receive, and analyze acoustic signals. The approach is non-invasive and relies on the interaction of sound with matter to produce information about structure, motion, and mechanical properties of tissues or materials.
In medicine, ultrasound-based imaging (ultrasonography) provides real-time visualization of internal structures by detecting echoes returned from
In industry, ultrasound supports non-destructive testing and materials evaluation, including flaw detection, thickness measurements, and weld
Technically, ultrasound-based systems rely on transducers (often piezoelectric), electronic pulsing, and signal reception. Image formation uses
Limitations include operator dependence, attenuation by bone or air, limited penetration depth for some tissues, and
