In a four-ring annular array, how many focal depths are typically utilized per scan line?

Explanation:
Focusing in an annular array is achieved by applying delays to each concentric ring so their beams converge at a chosen depth. Each ring acts as its own focal aperture, so the number of distinct focal zones you can form along a single scan line equals the number of rings. With a four-ring array, you can create four separate focal depths per scan line, improving resolution at multiple depths. Thus, four focal depths per line.
