iFab EasyScan
Quick start guide

This guide will provide a quick walk-through
when using iFab EasyScan for the rst time.
Please follow the instructions to ensure the best
outcome for your patient.
Start the application and login with you iCC credentials
• Start the application through the desktop icon. You will be
asked to pair your device with your iCC account. Use your
personal credentials to login. If you do not have an account yet
click on “Create an account” to sign up
Choose “General Scan” in the menu and start a new job
• Aer login select “General Scan” to start the sub-application
• Click on “New Job” in order to proceed and begin a new job
Assign job ID
• Assign an identifying job ID to proceed with “Start scanning”.
This can be any label preferred
• Note: Avoid specic names for data privacy reasons
• Please review and follow the additional scanning tips to ensure
the best scan result.
Select scan volume – in this example size S
• Select a scan volume in which the object has to be placed
before starting the scanning process. Only objects placed
within that scan volume are visible to the camera and captured
during scanning
• To select a scan volume that ts closest to the dimension of the
object select “Dene bounding box” in the right-hand menu
and apply the appropriate selection
• The application always starts with the last selection used

Download and install the iFab EasyScan application
If you have not yet installed the application you can download and
execute the installer at:
https://www.ifab-customer-center.com/Downloads
Please note: A limb model is available but not required to
learn how to use iFab EasyScan most efficiently and properly.
For this purpose the model is prepared with landmarks
needed to conduct a scan for custom liners.

Positioning the object and start scanning
• Dierent colors indicate whether the object is within or outside the detectable scan volume. Red indicates
the object is outside, green indicates the object is inside the detectable reach of the camera. Hold the cam-
era parallel to the surface of the object. Avoid tilting the camera which might eect that parts of the object
drop outside the detectable area
• When the object appears completely in green you can initiate the scan process clicking on “Start Scan”
Conduct and complete a scan
• Aer the countdown reaches zero the display changes and turns to show the
captured areas of the object. Complete the scanning process moving around
the object until it is fully captured
• Texture at specic areas of interest (e.g. landmarks) can be sharpened by
lingering above the area for a second and moving the camera close to it
• If tracking is lost the easiest way to regain tracking is returning to an already
captured area or to the starting point. As long as the position has not changed
the soware will recover the area and continue tracking

Light Conditions
• For optimal scan results, please avoid areas with too little or too much light (e.g. in front of a window or in
an unlit workshop).
• Normal room light conditions generate the smallest deviations of the scan and provide you with a good
texture quality
• The auto exposure of the scanner tries always to adapt the scanner settings to guarantee the best possible
outcome
• Warnings: There are two levels of warnings in case of overexposure:
•
• Visual feedback exposure: The object must be shaded completely in green before you start the scan to have
an optimal exposure. If the object is only partly green, it is overexposed. Point the scanner to the object and
wait a little bit. The auto exposure nds the correct level automatically and the object is colored green com-
pletely
General notes for scanning
• Move the scanner always facing parallel to the surface of the object
• The minimum operating distance of the scanner is 17 cm. If you are too close, the color eld in the area of
interest will be red until you increase the distance
• General behavior: The closer the scanner is to the target surface of the object, the better the data density for
reconstructing the surface
• The surface quality of the scan object will improve by scanning through multiple passes. The outcome is
smoother and the relevant anatomical structures are shown with higher accuracy
Major overexposure Overexposure No overexposure. Ready to go.

Review, cropping and finish a scan
• When the object has been captured completely, review the scan result clicking on “Pause scan”. In case of
uncaptured areas you can return to scanning mode and complete the scan
• Crop areas out of interest using the cropping tool in this section. Open the tool with the icon in the top le
corner. Draw a line between the area remaining aer cropping and the area to be cropped away. Invert the
direction of the cropping area if necessary. When satised with the selection apply the cropping
• ee
• Save the scan to the job list with “Finish Scan”. Note: Cropping cannot be undone aer this point
Complete the job and upload
• The completed job can be found in the job list waiting for na-
lization. Start nalization with the button . During this step
the upload package is created. Aer nalization upload the
job package to the iCC with the button . From there you can
access the scan le
• Uploaded jobs are moved into the archive. Jobs can be moved
back to the job list by clicking on the three dots
Access the scan file
• To access the scan le, switch to the iCC either through the
menu in the top le corner of the application or access the web-
site www.ifab-customer-center.com
• Go to the “Scan List” which can be found in the header under
your name
• Select the scan to be downloaded. Review the scan in 3D-view.
Start the download via the download icon and choose the
the le type of the 3D scan
• The scan will be downloaded to the directory on the local
machine as a zip package. Unpack the zip package to use the
3D le for further processing
