Chapter 4: Measurements and Calculations
You can measure for quick reference, or you can
measure within a calculation. You can perform
general calculations as well as calculations
specific to an exam type.
Measurements are performed on frozen images.
For references used, see Chapter 7, "References."
Measurements
You can perform basic measurements in any
imaging mode and can save the image with the
measurements displayed. (See "To save an
image" on page 42.) Except for the M Mode HR
measurement, the results do not automatically
save to a calculation and the patient report. If you
prefer, you can first begin a calculation and then
measure. See "Performing and saving
measurements in calculations" on page 51.
Some options may not apply to your system.
Options available depend on your configuration,
transducer, and exam type.
To save a measurement to a calculation and
patient report
1 With the measurement active (green), press
the
key.
CALCS
2 From the calculations menu, select a
measurement name.
Only measurement names available for the
imaging mode and exam type are selectable.
Save the calculation. (See "To save a
3
calculation" on page 51.)
To start a calculation before measuring, see
"Performing and saving measurements in
calculations" on page 51.
Working with calipers
When measuring, you work with calipers, often
in pairs. Results based on the calipers' position
appear at the bottom of the screen. The results
update as you reposition the calipers by using the
touchpad. In trace measurements, the results
appear after you complete the trace.
Outside a calculation, you can add calipers by
pressing the
key. You can have multiple
CALIPER
sets of calipers and can switch from one set to
another, repositioning them as needed. Each set
shows the measurement result. The active
calipers and measurement result are highlighted
green. A measurement is complete when you
finish moving its calipers.
Within a calculation, calipers appear when you
select from the calculations menu. (See "To select
from the calculations menu" on page 51.)
For an accurate measurement, accurate
placement of calipers is essential.
To switch the active calipers
Do one of the following:
• To switch the active caliper within a set,
press the
SELECT
• To switch the active set when measuring
outside a calculation, select Switch
on‐screen.
To delete or edit a measurement
With the measurement active (highlighted),
do one of the following:
• To delete, select Delete on‐screen.
• To edit, use the touchpad to move the
calipers.
Note: Trace measurements cannot be edited once set.
