Measurements and Calculations
Basic Measurements Operation
Measurements and calculations can be performed on zoomed images, stored images, real-
time images or frozen images.
Control
Description/Use
Caliper Button
Generic measurement tool are accessed in all imaging modes by pressing the Caliper button.
A subset of measurements is available in live imaging.
Users may ‘assign’ generic measurements to calculations after a measurement is complete.
• For instance, if a user measures the AP dimension of a thyroid lobe, and then decides to
include the measurement in the report, they can point to the measurement in the Results
Window.
• This will launch another window with calculations to choose from.
• Point to the desired calculation and the system will enter the data into the calculations
package.
Calc Button
Most presets have specific pre-defined measurements, calculations and reports associated
with them. These are accessed by pressing the Calc button on a frozen/cine image.
Note: Once the Calc button has been pressed, alternate calculation ‘libraries’ can be
accessed using OLED assigned to toggle libraries without changing Exam Presets.
Undo Button
The Undo button will generally undo the last measurement action.
• It can be used to remove a caliper that had been accidentally invoked.
It can be used to remove calipers that are part of a set (such as volume), removing the
calipers in the opposite order they were placed (last placed will be first removed).
Set Buttons
The Set buttons will launch and finalize the currently active measurement.
o For example, within the calc package they will launch the first caliper in the series
and enter the current measurement into the report.
o Within generic measurements they will lock the current measurement in place so
that an additional measurement can be invoked.
Select Button The Select button will provide ‘fine tuning’ of caliper placement.
o For example, if a ‘set’ of calipers is active while in Calcs or Caliper, pressing the
Select button will ‘switch’ trackball control between the two calipers.
