What term describes the ability of an imaging device to separate closely spaced objects?

• A. Resolution
• B. Penetration
• C. Duty factor
• D. Interference

Answer: (A)

Resolution is the ability of an imaging device to separate closely spaced objects. It describes how finely details can be distinguished; higher resolution means two adjacent structures can appear as distinct features rather than a single blur. This quality directly affects how well small or tightly spaced details are resolved in the image, which is crucial for accurate interpretation. Penetration concerns how deep the signal can travel, duty factor relates to how much of the time the device is emitting, and interference involves wave interactions that can create artifacts. So, the term that best describes the capacity to distinguish nearby objects is resolution.
