3.3.7 Ultrasound image acquisition
„ „ „ „ „
Patient's cooperation is helpful for successful ophthalmic
examination. Before going into examination, sufficiently
explain the examination procedure to the patient and
have him been sufficiently relaxed.
„ „
„ „ „ When applying the ultrasound gel to the probe, care is to
be taken not to cause air in the gel. If any unnecessary
echo occurs, add the gel sufficiently.
„ „ „ „ „
Since pressing of the FREEZE button to release the freeze
condition deletes all the moving images which have been
acquired, sufficient care must be taken before pressing
the FREEZE button.
