Automatic Standardize Orientation

Automatic Standerize Orientation (ASO) is an extension for 3D Slicer to perform automatic orientation either IOS or CBCT.

ASO Modules

ASO module provide a convenient user interfacer allowing to oriented different type of scans:

• CBCT scan
• IOS scan

The implementation is based on iterative closest point's algorithm.

ASO-CBCT

ASO-IOS

Module structure

Input file: The input has to be IOS with teeth's segmentation. The teeth's segmentation can be automatically done using the SlicerDentalModelSeg extension.

The input is folder containg IOS with the following extension:

.vtk

The IOS files need to have in their name the type of jaw (Upper or Lower).

Reference : The user has to indicate the path of the folder containing Gold Surface. In this folder has to have one vtk file per jaw. You can use your own Gold surface or download our Gold surface using the Download Reference Surface button in the module Input section.

Landmark selection : The user has to choose which teeth he wants to use as reference to oriented. We suggest using :

• Upper jaw : 4,5,6,11,12,13
• Lower jaw : 19, 20, 21, 27,28,29 This selection applies when you use the Suggest Teeth button.

Label surface: The user has to indicate array name of labels in the vtk surface. By default the name is PredictedID.
