Background:

Current surgical planning lacks patient-specific, real-time computational models.
Existing methods struggle with accurate interpolation of biological shapes for patient avatars.

Purpose of the Study:

To develop a new method for generating patient-specific computational avatars for surgery planning.
To enable real-time visual and haptic feedback for surgeons.

Main Methods:

Utilized computational vademecums, interpolated using manifold learning techniques.
Developed a specialized interpolation technique for biological shapes to ensure physiological accuracy.

Main Results:

Generated highly accurate patient avatars capable of kHz feedback rates.
Achieved precise patient-specific organ geometry representation.
Enabled both visual and haptic feedback for surgical simulations.

Conclusions:

The novel method successfully creates accurate, real-time computational patient avatars.
Manifold learning is crucial for interpolating biological shapes for non-physiological results.
These avatars significantly enhance surgical planning and training capabilities.
