In a test focused on elevational resolution, the targets are arranged to test resolution in which direction?

• A. Lateral direction
• B. Axial direction
• C. Elevational direction
• D. Temporal direction

Answer: (C)

Elevational resolution is about distinguishing objects that lie out of the imaging plane, in the direction perpendicular to the plane of the image. When targets are arranged in the elevational direction, you’re specifically testing how well the system can resolve two reflectors that sit above and below the imaging plane. In contrast, lateral resolution tests side‑to‑side separation within the image plane, axial resolution tests depth along the beam, and temporal direction isn’t a spatial axis in this context.
