- To enable real-time interaction with these vascular models.
Main Methods:
- Utilizing biplane X-ray angiograms as input data.
- Employing an image-processing system to extract vessel information.
- Building a display list for a high-function graphics system.
- Implementing real-time interaction via a vector-refresh display.
- Describing the Winchester Graphics System and its techniques.
Main Results:
- Blood vessel segments are represented as cylinders with appropriate diameters.
- Realistic raster representations provide insight into the overall vessel network topology.
- The system allows for interactive manipulation of the 3D vascular models.
Conclusions:
- The described method effectively generates interactive 3D computer graphics of in vivo blood vessels.
- This approach enhances the understanding of vascular network topology.
