To measure follicles
On each side, you can save up to three distance
measurements on a follicle, for up to 10 follicles.
If you measure a follicle twice, the average
appears in the report. If you measure a follicle
three times, the average and a volume calculation
appear in the report.
1 On a frozen 2D image, press the
2 From the calculations menu, select Follicle.
3 Do the following for each measurement you
want to take:
a From the calculations menu, select the
follicle number under Right Fol or Left Fol.
Position the calipers. (See "Working with
b
calipers" on page 47.)
c
Save the calculation. (See "To save a
calculation" on page 51.)
IMT calculations
WARNING:
To ensure high quality images, all
patient images must be obtained
by qualified and trained individuals.
To avoid patient injury, IMT results
should not be used as a sole
diagnostic tool. All IMT results
should be interpreted in
conjunction with other clinical
information or risk factors.
To avoid measurement errors, all
measurements must be of the
common carotid artery (CCA). This
tool is not intended for measuring
the bulb or the internal carotid
artery (ICA).
WARNING:

The following table shows available
measurements for IMT calculations. The IMT
measurement names are specified on the IMT
setup page. See "IMT Calculations setup" on
page 20.
Chapter 4: Measurements and Calculations
To avoid incorrect calculations,
verify that the patient information,
date, and time settings are
accurate.
To avoid misdiagnosis or harming
the patient outcome, start a new
patient information form before
starting a new patient exam and
performing calculations. Starting a
new patient information form
clears the previous patient's data.
The previous patient's data will be
combined with the current patient
if the form is not first cleared. See
"To create a new patient
information form"
on page 40.
