ophthalmologic ultrasound B-scan, diagnostic-A scan and biometry, even at FDA preenactment levels, no other use is intended or implied.
The system controls limit the output energy to within the parameters specified for its
intended purpose.
No control of ultrasound energy is available to the user other than the duration of
exposure.

4-4-3- Cineloop record :
The Cineloop will help the user to replay the sequence and to select the best image to
be saved for evaluation purposes : from the Cineloop record, the images will be saved
on the 10 available memories : #1 to #10 for each eye by using the 3 following screens :
The Cineloop is a powerfull tool that offers to the user a memorized sequence of the 4
seconds preceding the freezing action (the 4 seconds are divided in 200 frames of
20ms). Then, the user can review all the sequence in a loop and also choose one by one
the frames of the sequence.
After the acquisition is done by pressing the pedal, the Cinescan S indicates the
number of frames on the top of the
t he screen.
The displayed image is the last one memorized (example #150/150).
To review the whole sequence :
Pressing the two buttons of the TrackBall, or press [Pg Dn] key starts the automatic
image sequence.
To review the images one by one :
Press the right or the left button of the TrackBall.
If you keep pushing one button the
t he sequence will be displayed in slow motion (5 images

During the eye examination, with a non-frozen picture, for any Gain and any
position of the probe, you may see what would be the echogram successively at
" T+9.0dB", "T Gain"
Gain" and the previous Gain.
From any Gain displayed :
- PRESS the SPACE BAR and
and the Gain comes at "T" GAIN +9 dB:
example : "T+9.0 dB"
- PRESS again the SPACE BAR and the Gain go to the previous Gain :
"T - Xo dB".
- PRESS again the SPACE BAR and the Gain comes back at "T" GAIN :
example : "T=78.0 dB"
Note: This procedure is also available in the frozen cineloop
From the "T Gain" :
In the same way, you may see what would be the echogram at
"T + 9dB" Gain and then come back to the "T Gain".
-When the displayed Gain is "T" :
the Function Key F3: Displays : " Gain = T+9 "
-When the displayed Gain is "T + 9 dB" :
the Function Key F3: Displays :" Gain = T "
Note : when you are at "T + 9.0dB" the above procedure with the SPACE BAR works
also to shift to "T - Xo dB" and "T Gain".

which is the minimum threshold considered to apply the A1sign analysis. The
threshold can jump to 97% if the echo becomes higher.
Tracking Software :
The tracking is done during the time the pedal is pressed.
- It compares the selected echo amplitudes during the successive images
- Keeps in memory the image with the highest detected amplitude.
When the pedal is released the software switches to the result page showing the

12- QUANTITATIVE - II
12-1- PURPOSE
Echo amplitudes are only significant if they are maximized, when the exploration
axis is perpendicular to the tissue.
QUANT-II helps the user to find the best echogram maximized in amplitude for one
particular echo. This software will track in a non-frozen picture the selected echo
and store the image where its amplitude has been the highest.
A typical application is the differential diagnosis between a membrane and retina.
Three echograms will be stored containing the 3 maximized echoes :
- Membrane
- Pre-sclera
- Sclera
A following calculation will give the algebraic difference between these 3
amplitudes in dB :
- Diff M-S = Membrane amplitude - Sclera amplitude
- Diff Ps-S = Pre-sclera amplitude - Sclera amplitude
- Diff M-Ps = Membrane amplitude - Pre-sclera amplitude
These values will guide the ophthalmologist to make the right diagnosis.

For more experienced users, like for the
Immersion Technique, the height of the
echoes may not be sufficient criteria :
with a lower Gain the user may distinguish
the different layers and be able to
appreciate themselves the best position
of the probe.
The program :
- checks the echoes are between 5%

- must recognize the axial-length

14-9- STAT-2 CALCULATION
Remarks :
- The longer anterior chamber corresponds to a lower pression on the eye when
the Biometry is done in Contact Technique.
- The smallest vitreous is corresponding to the sharpest retinal echo, so a probe
position perpendicular to the retina.
- The "Stat-2" combines 2 echograms
echograms considering the following
following segments :
[ the longest value of (Cornea + Ant. Chamber + Lens) ]
+ [ the shortest vitreous length ].
Example below :
* the longest value of [Ant. Chamber + Lens ] :
see line #6 : 0.57 + 3.03 + 4.27 = 7.87 mm
* the shortest vitreous length :
see lines #4 : 16.81 mm
In this example : Stat-2 = 7.87 + 16.61 = 24.68 mm
Note : the result may have a difference of 0.01 mm because the unit takes the
numbers with more than 2 decimals for the calculation and then the rounded value is
made after the addition.
