Chapter 5 Flashcards
Spatial component
Where in the beam they are measuring
Temporal component
When they are sampling
ISP
When they measure the highest intensity in the beam it is labeled the spatial peak intensity
ISA
When they measure the average intensity across the beam it is labeled the spatial average intensity
IPA
When the instrument samples and averages the intensities recorded during the “on” time, this is referred to as the pulse average intensity
ITP
When the instrument samples the intensities during the on time but only reports the highest intensity recorded, this is referred to as the temporal peak intensity
ITA
When the instrument samples and averages the intensities recorded during the “on” and “off” time, this is referred to as the temporal average intensity
ISPTP
The highest intensity in the beam at the instant in time of its maximal value
ISPPA
The highest intensity in the beam sampled and averaged during the on time
ISPTA
The highest intensity in the beam sampled and averaged during the on and off time
ISATP
The average intensity across the beam at the instant in time of its maximal value
ISAPA
The average intensity across the beam sampled and averaged during the on time
ISATA
The average intensity across the beam sampled and averaged during the on and off time
intensities are examined most often and can be ranked from highest to lowest for pulsed ultrasound
ISPTP, IM, ISPPA, ISPTA, ISATA
beam uniformity coefficient or BUC
