General calculations
Within calculations, you can save measurement
results to the patient report. You can display,
repeat, and delete measurements from a
calculation. Some measurements can be deleted
directly from the patient report pages. See
"Patient report" on page 77.
Calculation packages depend on exam type and
transducer.
Calculations menu
The calculations menu contains measurements
available for the imaging mode and exam type.
After you perform and save a measurement, the
result saves to the patient report. (See "Patient
report" on page 77.) Also, a check mark appears
next to the measurement name in the calculations
menu. If you highlight the checked measurement
name, the results appear below the menu. If you
repeat the measurement, the results below the
menu reflect either the last measurement or the
average, depending on the measurement.
Menu items followed by ellipses (. . .) have
sub‐entries.
