21. Introduction to Shape Capture with the OMEGA Scanner21

22. OMEGA Scanner Officially Approved as a Class 1 Laser Device
No eye protection necessary
Patient movement accommodated during cranial scanning
Child can stay in parent’s lap during scanning 22

23. OMEGA Scanner LEDs illuminate reflective targets on the surface
Lasers are used to determine the contours for the surface
High resolution digital cameras “see” the lasers and record the position of the reflective targets 23

24. OMEGA Scanner Features
Capable of scanning directly over skin, sock, liner, plaster, or foam
Able to scan complex and intricate or detailed shapes and surfaces
Can merge two scans to create a shape
Can pause and resume during scanning session 24

25. Completely Portable! 25

26. Using the Scanner
Hold the Scanner approximately 12” from the surface to be scanned
Aim toward the center of the area to be scanned & press the trigger
Move the Scanner to follow the contours of the surface
Green light = OK
Red lights = too close or too far 26

27. Calibration/Optimizing the scanner
Optimizing should be performed whenever the scanner has been shipped or transported or if there is difficulty scanning in a surface.
If the scanner does not ‘travel’, optimizing once a month is sufficient.
Each scanner has it’s own specific optimizing plate that is located in the base of the scanner case.
Make sure the serial number on the scanner and the optimizing plate match before optimizing 27

• Frontozygomaticus [fz]: The most lateral point on the frontozygomatic suture (temporal crest of the frontal bone).
• Glabella [g]: The most prominent point in the medial sagittal plane between the supraorbital ridges
• Nasion [n]: The midpoint of the nasofrontal suture
• Opisthocranion [op]: The most prominent point on the occiput
• Subnasale [sn]: In the midline, the junction between the lower border of the nasal septum and the cutaneous portion of the upper lip.
• Tragion [t]: At the notch above the tragus of the ear where the upper edge of the cartilage disappears into the skin of the face.
• Vertex [v]: The highest point on the head with the head in the Frankfort horizontal plane 34

38. Creating and Saving Relief Pads
Relief Pads: Custom and Predefined
Provides the ability to create and save a specific region in a desired shape, size and amount of change.
A Relief Pad can be a build up or an excavation
Relief Pads can be created then saved for repeated use on future shapes.
Predefined or ‘saved’ relief pads can be edited for shape, size and amount of change. 38

39. Anatomy of a Relief Pad 1st: Identify Apex First
Perimeter of region
1st: Identify Apex First
Area of maximum amount of Build up or excavation.
2nd: Identify Outer Perimeter of Region
The area the build up or excavation will be blending or the ‘skived’ edge of the total area to be affected. 39

40. Assigning a Build Up 3rd: 4th: Determine the amount of build up
Using the slider, select the maximum amount of build up at the Apex
4th:
Save Relief Pad for future use
Relief Pads can be saved for repeated use by selecting the Save button on the Raise/Lower screen 40

41. When to use Relief Pads? Relief Pads: Custom and Predefined

When to use Symmetry: Copy Region? 42

43. What is Symmetry: Copy Region?
Symmetry: Copy Region Left/Right
Provides the ability to identify a region to be mirrored to the corresponding opposite side of the model. 43

44. How to use Symmetry: Copy Region?
1st: Identify Region
Identify the area to either be copied To or From. This example displays area to be copied From.
2nd: A mirror image of the region is created
A corresponding region is created in the mirror image of the original region on the opposite side of the model. Note: For best results, select Copy Surface Contour Only. 44

45. How to use Symmetry: Copy Region?
3rd:
Determine the copy percentage
Using the slider, select the amount of mirroring to take place, 0-100%. 45

46. When to use Symmetry by Region?
Symmetry : Copy Region Left/Right
Excellent modification tool option for:
Plagiocephalic deformities
Scaphocephalic deformities, ONCE side of head is modified to the desired shape and contour.
Contraindicated for Symmetrical Brachycephalic deformities 46

47. Shift Area What is Shift Area? How to use Shift Area?
When to use Shift Area? 47

48. What is Shift Area? Shift Area:
Works like a ‘heat gun’ tool to shift or move an area
The defined area can be edited
The greatest amount of changed is confined to single point apex
Can shift or move an area in more than one direction 48

49. How to use Shift Area? 1st: Identify Center of Shift
Area of maximum amount of Build up or excavation.
2nd: Identify Distance from Center
The area the build up or excavation will be blending or the ‘skived’ edge of the total area to be affected. 49

To further define or edit the shape of the area selected, pull and drag the blue lines using the left mouse button
4th:
Shifting the Area
Use the cursor or the arrows on the keyboard to shift the area as needed. Note: This is a ‘View Dependent’ tool, orientate the model as needed to pull and drag the surface of the model 50

51. When to use Shift Area? Shift Area:
Excellent modification tool option for any area that does not require an apex sustained over a large area. 51
