Imaging
• Back returns to the previous screen. If MBe is
on,
MBe is highlighted green and MBe appears
in the mode data area. Pressing MBe again
redisplays the MBe controls.
If MBe is on, the MB control is unavailable.
Additional recommendations
Avoid setting the gain too high when using MBe, as
unnecessarily high gain can cause artifacts in the
image. Also, respiratory and cardiac movement in
the image may cause bright pulsating artifacts.
If you use MBe frequently, consider using a shortcut
key to turn on the MBe control. For instructions to
program a shortcut key, see “A & B Key,
Footswitch setup” on page 15.
Imaging modes and exams
available by transducer
The transducer you use determines which exam
types are available. In addition, the exam type you
select determines which imaging modes are
available.
To change the exam type
 Do one of the following:
•Press the
EXAM key, and select from the
menu.
• On the patient information form, select from
the Type list under Exam. (See “Patient
information form” on page 36.)
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 biocompatibility
requirements.
WARNING:
To avoid injury to the patient, use
only an Orbital (Orb) or
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
Orb or Oph exam type is selected.
