==The Basics==
Data collection requires four pieces of equipment:
#an Analog-to-Digital Converter (A/D) board,
#a Pulser/Receiver (P/R),
#an ultrasonic transducer,
#a standard desktop or laptop computer to display the resulting information.

In a data collection, the P/R is triggered (often by a signal from the A/D board) which sends a burst of electricity to the ultrasonic transducer. This excites the transducer, which generates a burst of ultrasound. The returning ultrasound is sent back to the P/R, which sends the resulting waveform to the A/D board. The A/D board turns the waveform into digital information, which is processed into Peak Amplitude and Time of Flight results.

By continuously triggering the P/R while moving the transducer along an axis, we can generate results along a scan line. By stepping along a second axis after each scan line, a raster image of data is generated.

The trigger of the P/R is synchronized to the start of collection on the A/D board, so that the waveforms are always generated at the same point in time. In practice, this usually means that the A/D board itself sends the trigger to the P/R.
