Exam-Based Calculations; Abdominal Calculations - FujiFilm SonoSite X-Porte User Manual

Consider the following factors when performing volume flow measurements:
You should follow current medical practice for volume flow calculation applications.
The accuracy of the volume flow calculation largely depends on the user's measurement technique.
The factors identified in the literature that affect the accuracy are as follows:
Using the diameter method for 2D area
Precision in placing the caliper
Difficulty ensuring uniform insonation of the vessel
For more information about the considerations and degree of accuracy for volume flow measurements and
calculations, see the following reference:

To calculate volume flow
1 On a frozen 2D or Doppler trace, tap Calcs
If this control is hidden, tapping More Controls displays it.
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 form
before starting a new patient exam and performing calculations. Starting a new
patient 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
