What system component is most responsible for transmit focusing?

• A. Receiver
• B. Monitor
• C. Beam former
• D. Preprocessing

Answer: (C)

Transmit focusing is achieved by shaping the emitted beam so that waves from all transmit elements arrive in phase at a chosen focal point. The beam former handles this by applying precise time delays (and often amplitude weighting) to each element’s excitation. By tweaking these delays, the transmitted wavefront converges at a specific depth, steering and focusing the beam to enhance resolution at the focal point. The other components play different roles: the receiver manages the echoes after transmission and applies its own delays to focus in reception; the monitor is the display, and preprocessing handles data conditioning before image reconstruction. So, the beam former is the component that primarily enables transmit focusing.
