An a-scan, or amplitude scan, is a type of ultrasound imaging technique that produces a one-dimensional representation of the reflection amplitudes from various interfaces within a material. This method provides crucial information about the depth and internal structure of objects by displaying the time it takes for ultrasound waves to return to the transducer after encountering different materials. The a-scan technique is especially important in non-destructive testing and ultrasonic imaging, as it allows for precise measurements of material properties without causing damage.
congrats on reading the definition of a-scan. now let's actually learn it.
