Axial resolution is also known as depth resolution. Which of the following is a synonym for axial resolution?

• A. Depth resolution
• B. Lateral resolution
• C. Color resolution
• D. Temporal resolution

Answer: (A)

Axial resolution is the ability to distinguish two structures that lie along the path of the ultrasound beam, i.e., along the depth. Because it describes separation in depth, axial resolution is the same thing as depth resolution. The other terms describe different directions or concepts: lateral resolution is about side-to-side separation across the image and depends on beam width; temporal resolution relates to how quickly frames are collected (frame rate); color resolution isn’t the standard term used for this type of detail. So the synonym for axial resolution is depth resolution.
