A non-destructive testing technique where a single transducer is used to both transmit and receive waves or signals.

The number of ultrasound pulses transmitted by a transducer per unit of time. It represents the rate at which the ultrasound system repeats the transmission of pulses and is typically measured in hertz (Hz). By adjusting the PRF, the trade-off between inspection speed and sensitivity can be optimized.

A short duration of energy or signal characterized by a rapid change or burst of amplitude, often used in non-destructive testing to generate waves or signals for inspection purposes.

The transmission or movement of waves, signals, or energy through a medium or material, such as the propagation of ultrasonic waves through a test object during ultrasonic testing.

A device or transducer used in non-destructive testing to generate or receive waves or signals.

A statistical measure used in non-destructive testing to quantify the probability or likelihood of detecting a flaw or defect of a given size or type under specific inspection conditions and system capabilities.

An advanced firing technique utilized by PAUT instruments to achieve high-resolution imaging comparable to Total Focusing Method (TFM) imaging, but with significantly faster scanning speeds. In PWI, instead of individually firing each element during emission, a multi-element aperture (usually the full aperture of the probe) is selected, while in reception, elementary A-scans are recorded.

A wavefront that propagates in a uniform direction and exhibits a flat wavefront, characterized by parallel wavefronts with constant amplitude and phase.

A non-destructive testing technique that involves separate transmitting and receiving transducers or probes, where the transmitting probe emits waves and the receiving probe detects the reflected or transmitted waves.

A new advanced ultrasonic inspection technique that produces live total focusing method (TFM) images improving resolution and enhance flaw detection capabilities. This signal processing is based exclusively on the phase information of the elementary A-scans disregarding amplitude.
