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.

Bone graft harvested from the olecranon—an anatomic study

JSES International, 2022
Background: Bone grafts are widely used in orthopedic surgeries. Although the conventional iliac crest graft is still the largest source of cancellous and cortical-cancellous bone grafts, it may require a new surgical field and additional anesthesia.

Posterior shape models [PDF]

, 2013
We present a method to compute the conditional distribution of a statistical shape model given partial data. The result is a "posterior shape model", which is again a statistical shape model of the same form as the original model.
