What is the electronic steering process called in linear phased array imaging?

Explanation:
Electronic steering in a linear phased array imaging system is achieved through phasing. By applying precise time delays to each element, the emitted waves interfere constructively at a chosen angle, tilting the beam without moving the probe. This progressive delaying creates a virtual tilt so the main beam points in the desired direction. Steering is the general idea of changing the beam’s direction, scanning is the broader process of moving the beam across the field to form an image, and focusing refers to shaping the wavefront to converge at a point for better resolution. The specific technique that accomplishes steering electronically is phasing.
