The artifact related to the finite thickness of the ultrasound beam is associated with which resolution?

Explanation:
The issue is about the beam’s thickness in the elevational (out-of-plane) direction. Because the ultrasound beam has finite thickness rather than being a perfect thin sheet, echoes from tissue above or below the imaging plane contribute to the image. This slice-thickness (partial-volume) artifact degrades elevational resolution—the ability to distinguish structures in the direction perpendicular to the image plane. So the artifact described is tied to elevational resolution. The other terms describe different beam characteristics (focal and far-field behavior) or are not the standard way to name this particular artifact.
