High-quality slab-based intermixing method for fusion rendering of multiple medical objects.

Area of Science:

• Medical Imaging
• Computer Graphics
• Scientific Visualization

Background:

• Rendering multiple 3D medical objects is crucial for advanced applications.
• Heterogeneous data representations and configurations hinder efficient, high-quality rendering.

Purpose of the Study:

• To present a novel intermixing scheme for fusion rendering of multiple medical objects.
• To maintain real-time performance while enhancing rendering quality.

Main Methods:

• Developed an in-slab visibility interpolation method for subdivided slabs.
• Introduced virtual zSlab to extend boundaries into finite thickness slabs.
• Proposed a slab-based visibility intermixing method using virtual zSlab and interpolation within a new rendering pipeline.

Main Results:

• The proposed method achieves superior multiple-object rendering quality compared to conventional approaches.
• The intermixing scheme resolves aliasing and z-fighting issues for intersecting/overlapping surfaces.
• Demonstrated effectiveness in real clinical applications with advantages in rendering independency and reusability.

Conclusions:

• The novel slab-based intermixing scheme significantly enhances the visualization of multiple 3D medical objects.
• The method provides high-quality, real-time rendering solutions for complex medical data.
• Validated through case studies, the approach offers independent and reusable rendering capabilities for clinical use.
