What is virtual endoscopy?
The creation of inner views of tubular structures by means of virtual reality concepts.
What are the 4 technical requirements for CT virtual endoscopy?
1. data acquisition
2. image preprocessing
3. 3D rendering
4. image display and analysis
What does image preprocessing involve?
Image preprocessing involves the use of various noise filtering algorithms, image segmentation, cropping and cutting.
What is image segmentation?
Image segmentation can be done by the operator or automatically.
Certain images are selected and are windowed appropriately, while leaving other nonessential objects out. Then they are prepared for rendering.
