摘要

Ultrasonic arrays are now widely used in underwater sonar and in more than 25% of medical scans but their use in nondestructive testing (NDT) has been much less common. However, the cost of the design and manufacture of electronics specifically for use with ultrasonic arrays for NDT has recently fallen very significantly. In addition, adaptation of the processes to design and manufacture arrays for medical imaging has taken place for NDT. Thus, two of the main components for the use of arrays for NDT are now readily available. The third important component is the understanding and standardisation of inspection procedures that will allow common use in routine NDT. Work towards this has begun. As part of this process, the present article is intended to assist the NDT practitioner to extend his or her existing knowledge of ultrasound probes and their use to ultrasonic arrays.
