WARNING:
To prevent misdiagnosis or harm to
the patient, understand your
system’s capabilities prior to use.
The diagnostic capability differs for
each transducer, exam type, and
imaging mode. In addition,
transducers have been developed
to specific criteria depending on
their physical application. These
criteria include biocompatability
requirements.
To avoid injury to the patient, use
only an Ophthalmic (Oph) when
performing imaging through the
eye. The FDA has established lower
acoustic energy limits for
ophthalmic use. The system will not
exceed these limits only if the Oph
exam type is selected.
