ottobock iFab EasyScan A Quality for life

This guide will provide a quick walk-through when using iFab EasyScan

for the first time. Please follow the instructions to ensure the best outcome for your patient.

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.

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

1 Start the application and login with you iCC credentials

2 Choose “General Scan” in the menu and start a new job

After login select “General Scan” to start the sub-application
Click on “New Job” in order to proceed and begin a new job

3 Assign job ID

Assign an identifying job ID to proceed with “Start scanning”. This can be any label preferred
Note: Avoid specific names for data privacy reasons
Please review and follow the additional scanning tips to ensure the best scan result.

4 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 fits closest to the dimension of the object select “Define bounding box” in the right-hand menu and apply the appropriate selection
The application always starts with the last selection used

5 Positioning the object and start scanning

Different 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 camera parallel to the surface of the object. Avoid tilting the camera which might effect 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”

Correct placement

Object too close

Object too far away

6 Conduct and complete a scan

After 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 specific 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 software will recover the area and continue tracking

On tracking Off tracking

7 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:

Warning!
Overexposure

Warning!
Major 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 finds the correct level automatically and the object is colored green completely

Major overexposure Overexposure

No overexposure. Ready to go.

8 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 field 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

One pass Too close Multiple passes

9 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 left corner. Draw a line between the area remaining after cropping and the area to be cropped away. Invert the direction of the cropping area if necessary. When satisfied with the selection apply the cropping
