Use Cases

Endoscopy module in use

The typical use of this module is the creation of an animated fly-through of a structure such as the colon. With this module you can use interactively selected fiducial points as the control points for a 3D curve. This curve defines the flight path of the camera. The camera's speed and field of view can be controlled during playback.

Panels

Create a model

• Segment the target anatomy (colon, airways, etc.) using the Editor module or other segmentation tools
• Create a surface model using the Model Maker module
• Modify the generated model in the Models module: turn of Culling of Backface (to allow visualization of the inside of the surface)

Create a fly-through path

• Create a path model as a spline interpolation of a set of fiducial points.
• Pick the Camera to be modified by the path and the Fiducial List defining the control points.
• Clicking "Create path" will make a path model and enable the flythrough panel.

View the fly-through

• Turn off visibility of the fiducials in the Annotations module (so that they don't obstruct the view)
• You can manually scroll though the path with the Frame slider.
• The Play/Pause button toggles animated flythrough.
  • The Frame Skip slider speeds up the animation by skipping points on the path.
  • The Frame Delay slider slows down the animation by adding more time between frames.
• The View Angle provides is used to approximate the optics of an endoscopy system.
