To gain the full advantages of linear array scanning, typically a minimum of 32 elements are used. It is even more common to use 64 elements. More elements allow larger apertures to be stepped across the probe, providing greater sensitivity, increased capacity of focusing and wider area of inspection. The instrument must have the basic probe and wedge characteristics entered, either manually or via automatic probe recognition. Along with typical UT settings for the pulser, receiver and
measurement gate setup, the user must also set transducer beam and electronic steering (focal law) characteristics.
