COMPLETE QUESTIONS { GRADED A+}




Intensity Equation - ✔✔Power(watts) / beam area (cm^2)


What is Intensity - ✔✔the concentration of the power in a beam


Variations of intensity occur? - ✔✔In time and space


Ultrasound beam have variations of intensities depending on? - ✔✔Where in the

beam you are making a measurement, When the system is transmitting or receiving


Spatial - ✔✔Refering to distance or space


Peak - ✔✔The maximum value


Strenght of the sound beam varies depending on? - ✔✔Where you are measuring,

cross section


Isp - ✔✔Spatial Peak Intensity: the beam's intensity is at its maximum

, Isa - ✔✔Spatial Average Intensity: the average intensity across the beams entire

cross sectional area


Temporal - ✔✔Pulsed US does not have the same intesnity at different times


TP - ✔✔Temporal Peak: the instant in time of its maximal intensity


Ipa - ✔✔Pulsed average intensity: average throughout pulse duration


Ita - ✔✔Temporal Average Intensity: the average intensity throughout the pulse

repetition period(on and off time)


Im - ✔✔Intensity Max: the intensity of a sound beam averaged over the most

intense 1/2 cycle


Temporal intensities in order of strength - ✔✔Tempral Peak, Intensity Max,

Pulsed Average Intensity, Temporal Average Intensity


Isptp - ✔✔Spatial Peak Temporal Peak: location at max, intensity at the time that

the strongest part or the pulse passes


Isppa - ✔✔Spatial Peak Pulsed Average: Location at max, intensity averaged over

the transmit time
