Training models of anatomic shape variability [PDF]

Medical Physics, 2008
Learning probability distributions of the shape of anatomic structures requires fitting shape representations to human expert segmentations from training sets of medical images. The quality of statistical segmentation and registration methods is directly related to the quality of this initial shape fitting, yet the subject is largely overlooked or ...

Anatomic Analysis of Masseteric-to-zygomatic Nerve Transfer in Rat and Pig Models

Plastic and Reconstructive Surgery, Global Open, 2023
Background:. Nerve transfer from the masseteric branch of the trigeminal nerve is a widely performed procedure for facial reanimation. Despite achieving powerful muscle force, clinical and aesthetic results leave room for improvement.

Parametric Anatomical Modeling: a method for modeling the anatomical layout of neurons and their projections [PDF]

Frontiers in Neuroanatomy, 2014
Computational models of neural networks can be based on a variety of different parameters. These parameters include, for example, the 3d shape of neuron layers, the neurons' spatial projection patterns, spiking dynamics and neurotransmitter systems. While many well-developed approaches are available to model, for example, the spiking dynamics, there is

Anatomically based modeling [PDF]

Proceedings of the 24th annual conference on Computer graphics and interactive techniques - SIGGRAPH '97, 1997
We describe an improved, anatomically based approach to modeling and animating animals. Underlying muscles, bones, and generalized tissue are modeled as triangle meshes or ellipsoids. Muscles are deformable discretized cylinders lying between fixed origins and insertions on specific bones.
