Module Description
The Measurements module allows you to add rulers and angle widgets to the scene and they will be displayed and able to be manipulated in both the 3D and 2D windows.
Usage
In order to get the end points of the ruler or the angle to move along a selected model surface, you currently need to rotate the view so that the handle is rendered on top of the model, the next click will snap it to the model surface. If you move the model or slice plane, the measurement point won't move with it, the constraint only works when moving the end point handle. If you make the model or slice invisible, the end point cannot be moved, as the constraint will always be false.
When you add a new angle or affine transform widget, you have to click once in the 3D window to render the transform widget, and three times to place the angle widget end points. After that, you can move the widgets around by dragging the handles.
Use Cases, Examples
This module is especially appropriate for these use cases:
- Use Case 1: Useful for measuring tumor diameters.
- Use Case 2: Measuring angles between bones.
Examples of the module in use:
- Example 1: Attach/constrain end points of the widgets to volume slices to measure distances and angles between image features.
- Example 2: Attach/constrain end points of the widgets to models to measure distances and angles between 3D structures.

Development
Notes from the Developer(s)
- This module was added at version 3.5, and expanded at version 3.6, and it will not work unless Slicer3 is compiled with VTK5.6 or higher.
Dependencies
No other modules or packages are required for this module's use.
