SPATIAL + COMBINED INTENSITIES

Question 1

What is SPTP (Spatial Peak Temporal Peak)?

Answer 1

Highest intensity in space and time.

Question 2

What is SPPA (Spatial Peak Pulse Average)?

Answer 2

Highest spatial intensity averaged over pulse duration.

Question 3

What is SPTA (Spatial Peak Temporal Average)?

Answer 3

Highest spatial intensity averaged over entire PRP (transmit + receive). Most relevant for tissue heating.

Question 4

What is SATA (Spatial Average Temporal Average)?

Answer 4

Average intensity over full area and time.

Question 5

What is the order of combined intensities from highest to lowest?

Answer 5

SPTP > Imax > SPPA > SPTA > SATA.
