Chapter 5 Measurements and Calculations

Optimization of Measurement Accuracy
2D Mode
▶
Resolution is in proportion to the frequency of the probe.
▶
Penetration is in inverse proportion to the frequency of the probe.
▶
The highest resolution can be obtained at the focus of the probe where the ultrasound beam is nar-
rowest.
▶
The most accurate measurements can be obtained at the focus depth. The accuracy decreases as the
distance from the focus increases, widening the beam width.
▶
Using the zoom function or minimizing the depth display makes distance or area measurements
more accurate.
M Mode
▶
The accuracy of time measurements can be increased when the sweep velocity and the display for-
mat are set to high values.
▶
The accuracy of distance measurements can be increased when the display format is set to higher
values.
Doppler Mode
▶
It is recommended to use lower frequency ultrasound for measurement of faster blood ows.
▶
The size of the sample volume is limited by the axial direction of the ultrasound.
▶
Using lower frequency ultrasound increases penetration.
▶
The accuracy of time measurements can be increased when the sweep velocity is increased.
▶
The accuracy of velocity measurements can be increased when the vertical scale is set to smaller val-
ues.
▶
It is most important to use an optimal Doppler angle to enhance the accuracy of velocity measure-
ments.
