The energy of a pulsed ultrasound wave during its on-time is called what?

Explanation:
During the on-time of a pulsed ultrasound wave, the energy carried per pulse is called pulse energy. It represents the amount of energy delivered in each individual pulse, essentially the power during the pulse multiplied by its duration (E ≈ P_on × t_on). Since power relates to intensity and beam area, pulse energy reflects how much energy is delivered with each pulse. This differs from spatial energy, which would refer to energy distributed across space rather than accumulated over time. Temporal energy isn’t a standard term in this context and can be ambiguous. Duty cycle is the fraction of time the pulse is on within one cycle, not the energy itself.
