Biomechanical Behavior of Lithium-Disilicate-Modified Endocrown Restorations: A Three-Dimensional Finite Element Analysis

Ceramics, 2023
This study aimed to assess the biomechanical behavior of endocrown-restored mandibular molars according to “margin design” and “coverage extent” using finite element analysis (FEA).

Anatomical Models: a Digital Revolution [PDF]

Medical Science Educator, 2015
The use of three-dimensional (3D) anatomical models is ubiquitous in medical education. Medical educators rely on models to depict anatomical structures in a more efficient format than the cadaver; to move away from the clutter, discomfort, and complexity of a cadaveric dissection; and to clarify characteristics or functions of an anatomical structure ...

Nonparametric joint shape learning for customized shape modeling [PDF]

, 2010
We present a shape optimization approach to compute patient-specific models in customized prototyping applications. We design a coupled shape prior to model the transformation between a related pair of surfaces, using a nonparametric joint probability ...

Transcranial Direct Current Stimulation Optimization – From Physics-Based Computer Simulations to High-Fidelity Head Phantom Fabrication and Measurements

Frontiers in Human Neuroscience, 2019
BackgroundTranscranial direct current stimulation (tDCS) modulates neural networks. Computer simulations, while used to identify how currents behave within tissues of different conductivity properties, still need to be complemented by physical models ...

ASCON: Anatomy-aware Supervised Contrastive Learning Framework for Low-dose CT Denoising [PDF]

MICCAI 2023, 2023
While various deep learning methods have been proposed for low-dose computed tomography (CT) denoising, most of them leverage the normal-dose CT images as the ground-truth to supervise the denoising process. These methods typically ignore the inherent correlation within a single CT image, especially the anatomical semantics of human tissues, and lack ...
