Which term relates to time?

• A. Sound
• B. Spatial
• C. Temporal
• D. Stiffness

Answer: (C)

Temporal describes time. In ultrasound and many scientific contexts, it refers to timing aspects and how things change over time. For example, temporal resolution concerns how well rapid motion can be depicted, which is tied to frame rate. The other terms point to different domains: sound is the acoustic wave traveling through tissue, spatial relates to position and geometry in space, and stiffness is a material property describing resistance to deformation. Temporal comes from tempus, meaning time, which makes it the correct choice when the focus is on time-related aspects like motion and timing changes.
