Fixed depth focusing is also referred to as which term?

• A. Mechanical Focusing
• B. Conventional Focusing
• C. Fixed Focusing
• D. Dynamic Focusing

Answer: (B)

Fixed depth focusing uses a single, predetermined focal point set by the transducer’s design, so the beam remains focused at that depth during scanning. This is called conventional focusing. It’s the standard label for the traditional, non-electronic approach to focusing. Dynamic focusing, by contrast, adjusts the focus electronically for different depths, and mechanical focusing describes achieving a fixed focus through the transducer’s physical shape or lens. So conventional focusing best describes fixed depth focusing.
