Make sure the scanning environment meets the criteria detailed in “Scanning Environment” on page Double click the icon to start the NDI Krios software. The system will auto-connect by default. Alternatively, select File>Scanner Connection and select the com/serial port to which the system is connected. - Page 26 Note:The number of markers scanned (displayed at the bottom of the window) will show total number of markers to be scanned if a template is loaded. For example 82/256. Krios User Guide - Revision 03...

Set the required probing mode in Preferences, see “Preferences” on page Krios User Guide - Revision 03... - Page 30 Move the probe into the measurement volume. The probe will be represented dynamically in the main window and in the measurement volume. Note:You can also select Probe mode from the Probe button on the Scanner, Figure 1-1. Krios User Guide - Revision 03...

Page 32: Transform The Coordinate System
3.8 Transform the Coordinate System Once scanning and probing is complete, point cloud coordinates will be displayed in the Krios coordinate system. They are arbitrarily defined, based on the first four points scanned. You can choose to define an anatomically relevant coordinate system for the point cloud based on fiducial points using the Transform function. - Page 33 Once the Nasion, Left Preauricular Point and Right Preauricular Point have all be defined, select the Transform button on the toolbar to transfer the point cloud coordinates from the Krios coordinate system to the standard head coordinate system. (See Figure 3-8 an example of a completed Transform.)

Page 34: Labelling The Point Cloud
Select a marker in the point cloud. The selected marker turns yellow. Figure 3-9. In the Label Selected Marker pane, enter the label for the marker in the Reference text box. Krios User Guide - Revision 03... - Page 35 Select Template. In the resulting dialog, locate and double-click the .csv file containing the labelled template. Select Label. This presents the Label Assist view, with the labelled template on the left and the unlabelled point cloud on the right. See Figure 3-10. Krios User Guide - Revision 03...
- Page 36 Once you have four markers labelled, click off the point cloud. The template is applied to the unlabelled point cloud, which becomes fully labelled. See Figure 3-11. Krios User Guide - Revision 03...

Page 37: Export Results
To exit the Label Assist view, select Label again. Note:Dark grey unlabelled markers in the point cloud on the right following Step 5 indicate that Krios could not apply the template completely. This usually occurs when the initial four markers were labelled incorrectly or not spread out, or the transform was not performed correctly. -
