What is the advantage of using multiple transmit focal zones?

Explanation:
Focusing the ultrasound beam at several depths mainly improves how clearly structures are resolved side-to-side (lateral resolution) across a wider range of depths. A beam that is narrow at its focal point provides sharp lateral detail there, but away from that focal depth the beam widens and lateral resolution worsens. By using multiple transmit focal zones, the beam is narrowed at multiple depths, giving finer lateral detail across the image rather than just at one depth. The trade-off is that more transmit events are needed, which can reduce temporal resolution (frame rate), but the clear benefit is improved lateral resolution.
