Which of these intensities is the smallest?

Explanation:
Intensities in ultrasound are described by how they vary across space and over time. A peak means you take the highest value in that dimension, while an average means you average all values in that dimension. When you combine these, the descriptor that averages in both dimensions—space and time—will naturally be the smallest because it smooths out both spatial hotspots and temporal spikes. So the intensity that is spatially averaged and temporally averaged ends up being the smallest.
