Icon Prevention item Page

The necessary capacity of memory and hard disk are changed depending on the CPU in the personal computer or environment.
If the number of "Thread" in CPU is beyond 4, the processing may be delayed. Reduce the number of "Thread" to use this software.
When the object to be displayed is changed, start this software again. 18
When entering the patient ID through the 3D OCT-1, a bar code reader, a card reader, IMAGEnet, Multi-Viewer, etc., you must use only the alphabet, numerals and "-". Moreover, the following symbols cannot be used for the patient ID. " \ / : 'Space' * ? . <> | _ ! # $ % If you use a patient ID which does not meet the above conditions, the report cannot be output correctly from time to time.
When the photography data is displayed, "Normative Date" is displayed according to the patient's age at the photography date. However, it is limited as mentioned below.
• When the patient is under 19, "Normative Data" for the age of 20 is dis­played as reference.
• When the patient is over 81 years old, "Normative Data" for the age of 80 is displayed as reference.

When clicking the [Capture] button, sometimes the message "Ocular optical information value exceeded the compensated limitation. Default value shall apply." is displayed. In this case, access "Data Management" again. Click the [Edit patient infor­mation]" button and then the [Ocular Param.] button to correct "Ocular Parameters".
Sometimes the analysis function is not normally finished. In this case, the thumbnail is marked with "Fail".
For "B-2: Filter", the data of the image being displayed are used and so you cannot change the values of "Filter" directly.
The Measure Image function is based on the theoretical Gullstrand eye model. If the parameters of the actual patient's eye, such as the diopter or axial length, are different from the Gullstrand eye model, the measurement results may be different from the length and size in reality. The clinician will be solely responsible for the diagnoses and treatments based on the mea­surement results.
When modifying the data in optic disc analysis (refer to "4.2. Analyzing the Optic Disc" (P.132), the circle center is calculated again.

When you have reanalyzed the data modified manually, the data modified manually are erased and the "Disc" calculated automatically by the analysis mode set in the "OCTSet Analysis" tab on P.219 is applied.
As the result of automatic positioning, the fundus image is sometimes deformed to the oval shape on the fundus image display area (A-3). This is the result of the positioning process and there is no problem.
After analysis, the images are automatically positioned. If sufficient data required for overlapping are not provided, automatic positioning may not be done correctly.
When you have changed to the original tomogram after changing to two or more tomograms on the screen, you cannot return the edited layers to the original status by "Undo Modify". After carrying out "Exit Modify", the edited layers are decided and cannot be returned to the original status. However, in both cases, the data are not saved. If you return to the patient list screen without saving the data, you can start the operation from the beginning.
You cannot perform "Modify" for the image photographed by "OverSam­pling". When the "OverSampling" image is selected, the "Modify" function is OFF. For the photography with "OverSampling", refer to the instruction manual of the 3D OCT-2000 instrument body.

In the automatic optic disc analysis, sometimes errors occur due to the pho­tographed condition as shown below. In this case, using the menu "Disc Modify" displayed when selecting "Disc Segmentation", you can modify the analysis result. Refer to "Disc Modify" on P.95 in addition to this page.
When RPE was not detected correctly (If the patients blinked, his/her fixa­tion moved during scan, the tomogram overlaps the top edge of the image area, or the image quality is low, this may occur), the analysis result may not be correct.
The result of registration is as follows: Double-click an optional point on the two tomogram display areas, the two fundus image display areas and the upper right "Compare Window". The green line with a cross mark appears. (Pin-point Registration™) Sometimes this green line with a cross mark appears out of the 3D scan area (green frame).
There are two probable causes.
• On the two fundus image display areas, the fundus image is not aligned with the "Overlay" image correctly.
• On "Compare Window", the two "Shadowgram" images are not aligned with each other correctly.
138

To obtain the correct results, check the alignment on the two fundus image display areas and on "Compare Window". If the images are not aligned cor­rectly, carry out "Reposition" and repeat Step
The insufficient memory error may occur when selecting ten tomograms depending on the environment.

After clicking [Run] in the "Register" menu, Thickness Map is not displayed from time to time. In this case, click [On/Off] in the "Thickness" menu.
To display Thickness Map, the same layers in the selected image as those in "Image 1" must be analyzed. If the different layer has been analyzed, click the layer detection display selector buttons properly (refer to "A-2: Image Processing Controls area" on P.83) and analyze the necessary layer. Then, try the operation again to display Thickness Map.
Make sure that no other windows or images are blocking or placed over the Volume window during the movie-saving/recording procedure.
When batch export of the data including "_" (underbar) is performed for the patient ID which was created by the old version software, sometimes the data cannot be output with the filename that was set through "OCTSet".
When the analysis has failed, it is probable that the instrument did not take a picture correctly. It is possible that the analysis will be successful if the instrument takes a picture again.
To prevent your software from being infected with a computer virus through the network:
• Please prepare an antivirus software. Please use the antivirus software applicable to your use environment.
• TOPCON has already checked this instrument's operation when Trend Micro Virus Buster Corporate Edition (Ver10.0 Service Pack 1) of Trend Micro Incorporated is used.

[Grid] The Grid function displays the thickness between selected layers in each grid as the average value.(See "A-2: Image Processing Controls area"on P. 83.) The result of the comparison with normal data can also be displayed as a colormap.
Grid is defined as follows.
Grid type Grid definition
Rectangular • 10×10 grid where the length of one side is equal to 1/10 of 6mm (in "3D Vertical"
scan)
• 24×24 grid where the length of one side is equal to 1/24 of one side length of 3D scan area (in "3D Disc 512×128 6×6mm" scan)
• 6×6 grid where the length of one side is equal to 1/6 of one side length of 3D scan area (in 3D scan except the above-mentioned scans)
ETDRS The nine fields separated from the three concentric circles (diameter: 1, 3 and
6mm) by the ±45-degree line.
RNFL4 The area divided into four sections equally on the circumference. The circle radius
can be changed by selecting "On" of [On/Off] in the [Circle] menu.
RNFL6 The area divided into six sections equally on the circumference by 45 degrees in
vertical direction and by 90 degrees in horizontal direction. The circle radius can be changed by selecting "On" of [On/Off] in the [Circle] menu.
RNFL12 The area divided into twelve sections equally on the circumference. The circle
radius can be changed by selecting "On" of [On/Off] in the [Circle] menu.
"ETDRS" is valid for "Radial" and "3D: Macula, 6.0×6.0mm".
"RNFL4", "RNFL6" and "RNFL12" are valid for "3D: Disc, 6.0×6.0mm".
