*The velocity measurement is labeled either TAM for a manual trace or TAP for an automatic trace .
Measurements and calculations
To avoid injury to the patient, use only an Orbital (Orb) or Opthalmic (Oph)
exam type when performing imaging through the eye. The FDA has
established lower acoustic energy limits for opthalmic use. The system will not
exceed these limits only if the Orbital or Ophthalmic exam type is selected.
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.
