Which of the following is a key advantage of using phased array technology?

The ability to change the angle of the ultrasound beam electronically is a key advantage of phased array technology. This capability allows for precise control over the direction and focus of the ultrasound waves, which can be adjusted without moving the transducer physically. As a result, inspectors can obtain high-quality images and data from multiple angles in a single scan, significantly enhancing the efficiency and flexibility of the inspection process.

The electronic steering of the beam directly translates to better defect detection and characterization in a variety of geometries, including complex or curved surfaces, which is a significant improvement over traditional ultrasonic testing methods. This feature allows for the rapid adaptation to different inspection scenarios, making phased array systems versatile tools in non-destructive testing applications.
