Area of Science:

  • Medical Imaging
  • Computer Graphics
  • Image Processing

Background:

  • Volume rendering often suffers from object occlusions when relying solely on local image features.
  • Accurate visualization of complex anatomical structures is crucial in medical diagnostics.

Purpose of the Study:

  • To develop an improved volume rendering technique enhancing quality and speed.
  • To prevent object occlusions in volume rendering using segmentation data.
  • To enable clearer understanding of complex anatomical structures.

Main Methods:

  • Integrating original volume data with global model information from segmentation.
  • Utilizing an active contour model for region of interest extraction.
  • Proposing a volume rendering method for visualizing fuzzy surfaces.
