With the MAUT (Matrix Array Ultrasonic Testing) probe, you have transducer elements in two directions, both in the X and Y directions. As a result, the elements now cover an area rather than just a point (UT) or a slice (PAUT). This makes them a matrix array. Each of these elements is used for pulse-echo, and each element therefore produces an A-scan. This adds another dimension compared to PAUT and makes the result even easier to interpret. You now have volume data or 3D data and can view your results in addition to the B-scans and A-scans in a planar view (known as a C-scan) or in a 3D representation. This gives you much more flexibility in displaying NDT results and makes MAUT results much easier to interpret than UT and PAUT. This reduces the skill requirements for the operator and speeds up the inspection.
